[0021] In the turbine-driven fracturing well site layout, there is not only
turbine
engine using fuel gas, but also engine using fuel oil, which brings
inconvenience to both
environmental protection and control of the fracturing apparatus.
[0022] In the electrically-driven fracturing well site layout, all
apparatus is driven
electrically. If the generator or the variable-frequency drive is
malfunctioning, the entire well
site will be down and the fracturing operation will be interrupted, causing
danger. Compared
with turbine apparatus, electricity generating apparatus which uses gas or oil
as power fuel
reduces efficiency due to an intermediate step of energy conversion.
[0023] In the conventional fracturing well site layout, all apparatus uses
oil as power
fuel. Both oil combustion pollution and noise pollution are significant and
inevitable. There
are disadvantages such as high cost, low fuel utilization efficiency, loud
noise and high risk of
sudden halt of operation existed in the conventional fracturing well site
layout.
[0024] The existing turbine fracturing apparatus has at least one of the
following
shortcomings.
[0025] 1. Existing turbine fracturing apparatus, a diesel engine is
installed to provide
power for the whole machine, such as turbine engine start-up unit, lubricating
unit, cooling
unit, air supply unit, ventilating unit, and other units, which has
disadvantages such as high
cost and environmental pollution.
[0026] 2. In the turbine fracturing well site, the existing sand conveying
apparatus,
sand mixing apparatus, fracturing fluid mixing apparatus, and other apparatus
are all driven
by diesel engines, which also have the disadvantages of high cost, high noise,
and
environmental pollution.
[0027] 3. Existing all electric-driven well sites use grid power (grid
electricity),
variable-frequency drive, switch cabinet and other apparatus to provide power
for the electric
motor, and the electric motor drives a fracturing pump (plunger pump) to
perform a fracturing
operation. However, in the actual application process, there are problems such
as frequent
failures of electrical apparatus like the variable-frequency drive and etc.
The risk of operation
shutdown is high, which seriously affects the efficiency of wellsite
operations.
[0028] 4. The well site occupies a large space.
Date Recue/Date Received 2022-01-05
[0029] 5. The power supply of existing well sites is unstable, and there
are serious
unreliability hidden dangers for fracturing operations, especially plunger
pump operations.
[0030] 6. Existing turbine fracturing apparatus uses motors as driving
components for
lubrication, cooling, turbine engine startup, and air supply, and must be
equipped with a
hydraulic unit. The hydraulic unit needs a power source, and a power device,
such as an
engine, that provides high-pressure for the hydraulic unit is further
required. The engine is
used as an accessory apparatus to provide pressure for the hydraulic unit. In
such a case, not
only the apparatus has more accessories, but also the cost of the apparatus is
increased.
[0031] 7. The existing turbine engine uses a hydraulic starting form, and
the auxiliary
engine must be started before starting the turbine engine.
[0032] FIG. lA is a schematic diagram of a turbine fracturing apparatus,
and FIG. 1B
is a schematic diagram of a principle of a turbine fracturing hydraulic
system. As illustrated
in FIG. 1B, the solid line refers to the hydraulic fluid, the arrow refers to
the direction of the
hydraulic fluid, and the dashed line refers to the mechanical connection
between the
components. Referring to FIG. lA and FIG. 1B, the turbine fracturing apparatus
001 includes
a vehicle body 100, a hydraulic oil tank 01, a fuel tank 02, an engine 03, a
plunger pump 1, a
turbine engine 2, a cooler 3, a muffler 4, a reducer 6, and lubricating oil
tank 8 that are
provided on the vehicle body 100. For example, the engine 03 includes a diesel
engine, and
the fuel tank 02 includes a diesel tank.
[00331 As illustrated in FIG. 1A, the plunger pump 1 is connected with the
turbine
engine 2 through the reducer 6. A coupling 5 is provided between the plunger
pump 1 and the
reducer 6. The reducer 6 includes a gearbox and a gear structure located in
the gearbox. One
end of the turbine engine 2 is connected with the plunger pump 1 through the
gearbox to
drive the plunger pump to suck in low-pressure fracturing fluid and discharge
a high-pressure
fracturing fluid, that is, the plunger pump 1 is configured to pressurize the
fracturing fluid to
foon high-pressure fracturing fluid. As illustrated in FIG. 1A, the other end
of the turbine
engine 2 is connected with an exhaust assembly 49, which includes an exhaust
pipe 9 and a
muffler 4; the exhaust pipe 9 is connected with the turbine engine 2 and is
configured to
discharge exhaust gas. The muffler 4 is connected with the exhaust pipe 9 and
is configured
to reduce exhaust noise. The fuel tank 02 supplies oil to the engine 03, the
engine 03 is
11
Date Recue/Date Received 2022-01-05
connected with a hydraulic pump 04 (not illustrated in FIG. 1A, refer to FIG.
1B), and the
hydraulic oil tank 01 is connected with a hydraulic pump 04 (refer to FIG.
1B). For example,
the fracturing fluid may also be referred to as a fracturing liquid.
[0034] FIG. lA illustrates a muffling compainnent 7. As illustrated in FIG.
1A, the
turbine engine 2 and the reducer 6 are located in the muffling compartment 7,
and the
muffling compartment 7 is configured to reduce noise. FIG. lA also illustrates
the
high-pressure manifold 101. For example, the high-pressure manifold 101 is
configured to
allow high-pressure fracturing fluid to flow therein.
[0035] As illustrated in FIG. 1B, the hydraulic pump 04 supplies oil to the
actuating
motor 05 of the turbine fracturing apparatus. The actuating motor 05 includes
a start-up
electric motor 051, a lubricating electric motor 052, a cooling electric motor
053, and a
hydraulic motor 054. The lubricating electric motor 052 is connected with the
lubricating
pump 11 to drive the lubricating pump 11 to convey the lubricating oil from
the lubricating
oil tank 8 to the plunger pump 1, the reducer 6, and the turbine engine 2 for
lubrication. For
example, the vehicle body 100 includes a semi-trailer, but is not limited
thereto.
[0036] As illustrated in FIG. 1B, the cooling electric motor 053 drives the
cooler 3,
the start-up electric motor 051 is connected with the turbine engine 2 to
start up the turbine
engine 2, and the hydraulic motor 054 drives the hydraulic air compressor 06.
[0037] Turbine fracturing apparatus 001 uses an auxiliary engine as a power
source to
drive the lubrication, cooling, turbine engine start, air supply and other
components of the
whole machine. The shortcomings of the turbine fracturing apparatus 001 are:
1) the size of
the whole vehicle is long, which is not conducive to well site transportation
and market
promotion; 2) using diesel as auxiliary power fuel, causing certain
environmental pollution; 3)
low efficiency of the hydraulic unit.
[0038] Therefore, there is a need to provide a fracturing apparatus and a
fracturing
system having the fracturing apparatus to at least partially solve the above-
mentioned
problems.
100391 The embodiment of the present disclosure provides a fracturing
apparatus and
a fracturing system with the fracturing apparatus, which can be used for field
fracturing
operation of oil and gas fields. For example, the fracturing apparatus and the
fracturing

system with the fracturing apparatus can be used for the well site layout and
process
implementation scheme of hydraulic fracturing operation, and can be used in
the fracturing
well site, mainly for the operation of turbine fracturing well site.

electrically driven and directly driven by the power supply. For example, no
hydraulic unit is
provided in the auxiliary unit 500. For example, the auxiliary unit 500 is not
provided with a
hydraulic pump, nor is a fuel tank and an engine for driving the hydraulic
pump provided.
Compared with the fracturing apparatus 001 illustrated in FIG. lA and FIG. 1B,
the
fracturing apparatus la provided by the embodiment of the present disclosure
does not have
the hydraulic pump 04, nor does it have the fuel tank 02 and the engine 03 for
driving the
hydraulic pump 04.
[0045] In the fracturing apparatus la provided by the embodiment of the
present
disclosure, the auxiliary unit is directly driven in an electrically driven
manner. Each
auxiliary unit can be provided with an electric motor, which can realize point-
to-point driving,
minimize energy waste, the electric motor can be powered off without inputting
power
thereto when it is not at work, so as to realize comprehensive and reasonable
distribution of
energy consumption.
[0046] According to the embodiment of the present disclosure, the turbine
engine is
used as the main power source for fracturing operation, and the power supply
is used to
provide power for the auxiliary unit in an electrically driven manner, which
can make the
overall layout of fracturing apparatus more compact.
[0047] For example, in some embodiments, the turbine engine is driven by
natural gas,
the fracturing apparatus as a whole uses clean energy, there is no
environmental pollution,
and the maximum utilization of efficiency can be realized.
[0048] For example, as illustrated in FIG. 2A, the turbine engine 2 is
connected with
the plunger pump 1 through a gearbox, which is used to drive the plunger pump
1 to operate
to convert low-pressure fracturing fluid into high-pressure fracturing fluid
and then convey
the high-pressure fracturing fluid to the wellhead. For example, as
illustrated in FIG. 2B, the
turbine engine 2 is provided with a start-up unit 501, the start-up unit 501
includes a start-up
electric motor 51 having a main function of starting up the turbine engine, so
as to realize the
normal operation of the turbine engine and provide power for the fracturing
pump operation.
For example, as illustrated in FIG. 2B, the start-up electric motor 51 is
configured to directly
start up the turbine engine 2, and the start-up electric motor 51 is directly
connected with the
turbine engine 2. Of course, in other embodiments, the start-up electric motor
51 can be used
14
Date Recue/Date Received 2022-01-05
to drive a hydraulic unit which is used to start up the turbine engine. For
example, the
hydraulic unit includes a hydraulic pump and a hydraulic motor.
[0049] For example, in some embodiments, the turbine engine 2 is driven by
fuel or
gas, and is directly started up in an electrically driven manner. For example,
in the case where
the turbine engine 2 is driven by fuel, a fuel tank is provided.
[0050] For example, as illustrated in FIG. 2A and FIG. 2B, the lubricating
unit 502
includes a lubricating pump 11, a lubricating oil tank 8, and a lubricating
electric motor 52.
The main function of the lubricating electric motor 52 is to provide a driving
force to the
lubricating oil, so that the lubricating oil in the lubricating oil tank 8 can
be delivered to the
lubricating point. For example, the lubricating electric motor 52 is
configured to drive the
lubricating pump 11 to deliver the lubricating oil in the lubricating oil tank
8 to the
lubricating point. For example, the lubricating point may be at least one of
the plunger pump
1, the turbine engine 2, and the reducer 6. For example, the lubricating point
may also include
an electric motor. For example, as illustrated in FIG. 2B, the lubricating
electric motor 52 is
directly connected with the lubricating pump 11. For example, the lubricating
pump 11 is
directly driven in an electrically driven manner.
[0051] For example, as illustrated in FIG. 2B, the cooling unit 503
includes a cooling
electric motor 53 and a cooler (cooling part) 3. The main function of the
cooling electric
motor 53 is to provide a driving force to the cooler 3, so as to cool the
lubricating oil. For
example, the cooling electric motor 53 is configured to drive the cooler 3 to
provide a driving
force for cooling the lubricating oil. For example, the cooler 3 is configured
to cool the
lubricating oil and reduce the temperature of the lubricating oil. For
example, as illustrated in
FIG. 2B, the cooling electric motor 53 is directly connected with the cooler
3. For example,
the cooler 3 is directly driven in an electrically driven manner. For example,
the cooler 3
includes a fan, but is not limited thereto.
[0052] For example, as illustrated in FIG. 2B, the air supply unit 504
includes an air
supply electric motor 54 and an air compressor 13. For example, the air supply
electric motor
54 is directly connected with the air compressor 13. The air compressor 13 is
directly driven
in an electrically driven manner. The air compressor 13 is an electrically
controlled air
compressor. The air supply electric motor 54 mainly provides a driving force
for the air
Date Recue/Date Received 2022-01-05
compressor 13 and provides air (compressed air) with a certain pressure for
the turbine
engine, thus realizing the use of dual fuels for the turbine engine.
100531 For example, as illustrated in FIG. 2B, the ventilating unit 505
includes a
ventilating electric motor 55 and a ventilating part 14. For example, the
ventilating electric
motor 55 is directly connected with the ventilating part 14. The ventilating
part 14 is directly
driven in an electrically driven manner. The ventilating electric motor 55 is
configured to
drive the ventilating part 14. For example, the ventilating part 14 includes a
ventilating blade,
but is not limited thereto. For example, the ventilating unit 505 is
configured to reduce the
temperature of the air in the muffling compartment 7, so that the air in the
muffling
compaitment 7 can be circulated. For example, the ventilating part 14 includes
a fan, but is
not limited thereto.
[0054] For example, the power supply 12 supplies electric power to the
lubricating
electric motor, the cooling electric motor, the ventilating electric motor,
the air supply electric
motor, and the start-up electric motor, respectively. For example, the power
source 12 may be
at least one selected from the group consisting of a generator, a grid
electricity, a fuel cell and
an energy storage battery.
[0055] For example, as for the start of turbine engine, the existing
fracturing
apparatus is driven by motor, starting the motor needs to consume a part of
power, and the
hydraulic unit itself also consumes a part of power, which leads to the
increase of energy
consumption of the whole apparatus. However, if the turbine engine is driven
by electric
motor, and is controlled by variable-frequency driving, point-to-point driving
can be realized,
and the energy waste can be minimized. After starting is completed, the
electric motor can be
cut off, and then there is no need to input power to this electric motor, so
as to realize
comprehensive and reasonable distribution of energy consumption. The same is
true for other
auxiliary units, which can be referred to the description of the start-up unit
and will not be
repeated herein.
[0056] According to the present disclosure, an auxiliary engine can be
omitted from
the fracturing apparatus, and hydraulically driven actuators are all
substituted by electrically
driven actuators, which has at least one of the following advantages.
16
Date Recue/Date Received 2022-01-05
[0057] 1) It is possible to reduce the size of the carrier and make the
layout of the
fracturing apparatus more compact, which facilities wellsite transportation
and market
promotion.
[0058] The turbine fracturing apparatus has a higher unit-power compared
with the
conventional diesel driven apparatus, which greatly saves the occupied space
at the well site.
The diesel engine and the fuel tank thereof are removed, and other components
such as the
hydraulic oil tank and the hydraulic motor are removed, such that the number
of components
and parts of the entire apparatus is reduced, realizing size reduction of the
fracturing
apparatus. The design is optimized with the function remaining unchanged and
the size being
reduced. It is possible to realize large-scale operation at small well field
because the layout of
the well site is more convenient.
[0059] 2) The entire apparatus uses clean energy, and environment
pollution is
eliminated.
[0060] For example, in some embodiments, the turbine engine uses natural
gas and
the remaining components are all driven by electric motors. The power source
of the electric
motors can be electrical power, all of which are clean energy.
[0061] 3) Each actuator can be equipped with an electric motor configured
for driving.
This solution minimizes the energy waste caused by the hydraulic system
itself, thereby
achieving maximum efficiency.
[0062] For example, the turbine engine is started by a motor in the
existing fracturing
apparatus, the start-up of the motor needs to consume a part of power, and the
hydraulic unit
also needs a part of power, which leads to an increase in energy consumption
of the whole
apparatus. While if the turbine engine is started by an electric motor and is
controlled by a
variable-frequency driving, thereby achieving point to point driving with less
waste of energy
consumption. The electric motor can be powered off without being input with
power after the
start-up of the turbine engine, thereby realizing a comprehensive and
reasonable distribution
of energy consumption.
[0063] 4) All the lubricating, cooling, turbine engine start-up, and air
supply of the
turbine fracturing apparatus are driven by electric motors. For example, these
electric motors
can be powered by a 380V power supply which has a wide range of sources, such
as energy
17
Date Recue/Date Received 2022-01-05
storage battery, fuel cell, grid electricity and generator, etc. There is no
need for the 10kV
high voltage power at the well site, thereby improving reliability.
[0064] For example, the conventional electrically-driven well site is
equipped with at
least four power generation assemblies with a predetermined power. Once the
power
generation assemblies are malfunctioning, the entire well site will be down.
While according
to the present disclosure, only one power generation assembly with the
predetermined power
can meet the electricity demand of the well site, and the plunger pump with
the largest energy
consumption demand uses clean energy such as natural gas as fuel. This
optimizes energy
utilization in fracturing operations, reduces the failure rate of well site
and increases
reliability of fracturing operations. Of course, in other embodiments, the
plunger pump can
also use diesel as fuel. For example, the predetermined power of the above-
mentioned power
generation assembly may be less than IMVV, or the predetermined power of the
power
generation assembly may be greater than or equal to IMW and less than or equal
to 8MW.
For example, the conventional electric drive well site needs to be equipped
with four power
generation assemblies each of which with a power of 5.8MW, while according to
the
embodiment of the present disclosure, only one power generation assembly with
a power of
5.8MW is needed to meet the well site power demand. Of course, the power of
power
generation assembly can be adjusted as needed.
100651 FIG. 3A is a schematic diagram of a fracturing apparatus provided by
an
embodiment of the present disclosure. The arrow direction in FIG. 3A is the
air flow direction.
As illustrated in FIG. 3A, the fracturing apparatus lb includes a plunger pump
1 and a turbine
engine 2. The turbine engine 2 is configured to drive the plunger pump 1. One
end of the
turbine engine 2 is connected with the plunger pump 1 through the reducer 6 to
drive the
plunger pump to suck in low-pressure fracturing fluid and discharge high-
pressure fracturing
fluid, that is, the plunger pump 1 is configured to pressurize the fracturing
fluid to form
high-pressure fracturing fluid.
[0066] For example, as illustrated in FIG. 3A, the cooler 3 is configured
to cool the
lubricating oil to lower the temperature of the lubricating oil. As
illustrated in FIG. 3A, the
cooler 3 is arranged at a side of the muffler 4. For example, the cooler 3 is
arranged directly
above the plunger pump 1. Because the height of the vertical part of the
muffler 4 is large,
18
Date Recue/Date Received 2022-01-05
although the air discharged from the cooler 3 in FIG. 3A is upward, it can
also be seen that
the air discharged from the cooler 3 flows toward the muffler 4, so that the
flow speed of the
air outside the muffler 4 can be increased, which is conducive to rapid
reduction of the
temperature. Arranging the cooler 3 on plunger pump can reduce the length of
lubricating oil
pipeline, save space layout and make the whole apparatus more compact.
[0067] For example, in the embodiment of the present disclosure, referring
to FIG. 2B
and FIG. 3A, the lubricating oil pipeline is arranged to pass through various
lubricating points,
and is connected with the lubricating pump 11, and is heat-dissipated through
the cooler 3.
For example, the lubricating pump 11 is driven by the lubricating electric
motor 52.
[0068] As illustrated in FIG. 3A, the other end of the turbine engine 2 is
connected
with an exhaust assembly 49 which includes an exhaust pipe 9 and a muffler 4.
The exhaust
pipe 9 is connected with the turbine engine 2 and configured to exhaust an
exhaust gas. The
muffler 4 is connected with the exhaust pipe 9 and is configured to reduce
exhaust noise. For
example, the turbine engine 2 includes the exhaust pipe 9 to which the muffler
4 is connected.
For example, in a direction from a position close to the turbine engine 2 to a
position away
from the turbine engine 2, the pipe diameter of the exhaust pipe 9 gradually
increases to
facilitate exhaust gas discharge.
[0069] For example, the fracturing apparatus lb further includes a power
supply 12, a
vehicle body 100, and an auxiliary unit 500. For the power supply 12, the
vehicle body 100
and the auxiliary unit 500, the previous description of the fracturing
apparatus la can be
referred and will not be repeated herein.
[0070] In some embodiments, as for the cooling unit 503, the cooler 3 of
the
fracturing apparatus lb is also directly connected with the cooling electric
motor, which is
directly driven by the cooling electric motor, just like the fracturing
apparatus la.
[0071] In some embodiments, as for the start-up unit 501, the turbine
engine 2 of the
fracturing apparatus lb is directly connected with the start-up electric motor
51, which is
directly driven by the start-up electric motor 51, just like the fracturing
apparatus la.
[0072] In some embodiments, as for the lubricating unit 502, the
lubricating pump 11
of the fracturing apparatus lb is directly connected with the lubricating
electric motor 52,
19
Date Recue/Date Received 2022-01-05
which is directly driven by the lubricating electric motor 52, just like the
fracturing apparatus
la.
[0073] In some embodiments, as for the air supply unit 504, the air
compressor 13 of
the fracturing apparatus lb is directly connected with the air supply electric
motor 54, which
is directly driven by the air supply electric motor 54, just like the
fracturing apparatus la.
[0074] In some embodiments, as for the ventilating unit 505, the
ventilating part 14 of
the fracturing apparatus lb is directly connected with the ventilating
electric motor 55, which
is directly driven by the ventilating electric motor 55, just like the
fracturing apparatus la.
[0075] In some embodiments, at least one of the cooler 3, the start assist
of the
turbine engine 2, the lubricating pump 11, the air compressor 13, and the
ventilating electric
motor 55 of the fracturing apparatus lb is directly connected with its
corresponding electric
motor and is directly driven by the electric motor.
[0076] In the fracturing apparatus provided by the embodiment of the
present
disclosure, the actuators, such as the cooler 3, the start assist of turbine
engine 2, the
lubricating pump 11, the air compressor 13, the ventilating part 14, etc., are
directly driven by
electric motors. Compared with the way in which electric motors drive
hydraulic units,
hydraulic units the drive cooler 3, the start assist of turbine engine 2, the
lubricating pump 11,
the air compressor 13, the ventilating part 14, the energy consumption is low,
and the electric
motors can be powered off when not driving the actuators, which is conducive
to the
realization of a comprehensive and reasonable distribution of energy
consumption.
[0077] FIG. 3B is a schematic diagram of a fracturing apparatus provided by
an
embodiment of the present disclosure. As illustrated in FIG. 3B, compared with
the fracturing
apparatus lb illustrated in FIG. 3A, in the fracturing apparatus lbl, the
cooler 3 is inclined so
as to facilitate the air discharged from the cooler 3 to move to the muffler
4. For example, in
order to facilitate the air discharged from the cooler 3 to move to the
muffler 4 and facilitate
the installation of the cooler and the lubricating oil pipeline, the
inclination angle al of the
cooler 3 is in a range from 10 to 30 degrees. For example, the cooler 3 is
disposed obliquely
with respect to the surface of the vehicle body 100. For example, the cooler 3
is disposed
obliquely with respect to an axis a0 of the plunger pump 1. For example, the
air outlet side of
the cooler 3 is inclined toward the muffler 4.

100781 FIG. 3C is a schematic diagram of a fracturing apparatus provided by
an
embodiment of the present disclosure. As illustrated in FIG. 3C, compared with
the fracturing
apparatus lb illustrated in FIG. 3A, the fracturing apparatus 1b2 is provided
with a protective
baffle 151 outside the muffler 4. For example, the protective baffle 151 may
be provided with
a weight-reducing hole (not illustrated in the figure). The weight-reducing
hole in the
protective baffle 151 can refer to the hole 150 in the baffle 15 mentioned
later. The protective
baffle 151 can play a protective role. The protective baffle 151 is at least
provided at least one
side of the muffler 4. For example, the baffle 151 may be provided at the
other three sides of
the muffler 4 except the side connected with the exhaust pipe.
100791 FIG. 4 is a schematic diagram of a fracturing apparatus provided by
another
embodiment of the present disclosure. The fracturing apparatus lc differs from
the fracturing
apparatus lb in that the cooler 3 is arranged at a side of the muffler 4. As
illustrated in FIG. 4,
the air discharged from the cooler 3 flows toward the muffler 4. That is, the
cooler 3 is
configured such that the air discharged from the cooler 3 flows toward the
muffler 4. For
example, as illustrated in FIG. 4, the cooler 3 is arranged at the side of the
muffler 4 away
from the exhaust pipe 9. For example, as illustrated in FIG. 4, the cooler 3
is adjacent to the
muffler 4.
[0080] Because the temperature of the outer surface of the muffler 4 is
higher than
that of the air discharged from the cooler 3, the air discharged from the
cooler 3 can flow
toward the muffler 4, thereby increasing the flow speed of the air outside the
muffler 4,
realizing rapid temperature reduction and air reuse.
100811 FIG. 5A is a schematic diagram of a fracturing apparatus provided by
another
embodiment of the present disclosure. FIG. 5B is a schematic diagram of a
baffle in
fracturing apparatus provided by an embodiment of the present disclosure. FIG.
5C is a
schematic diagram of the arranging position of the baffle in a fracturing
apparatus provided
by an embodiment of the present disclosure. FIG. 5D is a schematic diagram of
the arranging
position of the baffle in a fracturing apparatus provided by another
embodiment of the present
disclosure.
[0082] For example, compared with the fracturing apparatus lc illustrated
in FIG. 4,
the fracturing apparatus ld illustrated in FIG. 5A is provided with a baffle
15. For example,
21
Date Recue/Date Received 2022-01-05
in order to avoid the influence of the outer surface temperature of the
muffler 4 on the cooler
3, a baffle 15 is arranged outside the muffler 4, and the baffle 15 is located
at a positon closer
to the muffler 4. For example, as illustrated in FIG. 5A, FIG. 5C and FIG. 5D,
the baffle 15 is
arranged outside the muffler 4 and at least partially between the muffler 4
and the cooler 3.
The arrangement of the baffle 15 is beneficial to the maximum reduction of
thermal radiation.
[0083] Referring to FIG. 3A, FIG. 4 and FIG. 5A, in order to facilitate the
arrangement of the cooler 3, the cooler 3 is arranged at a side of the muffler
4.
[0084] As illustrated in FIG. 4 and FIG. 5A, the cooler 3 is arranged at a
side of the
muffler 4, so that a side (air outlet side) SO of the exhaust air of the
cooler 3 faces the muffler
4, so that the exhaust air of the cooler 3 flows toward the muffler 4, and the
flow speed of the
air outside the muffler 4 is increased, thereby realizing rapid temperature
reduction and air
reuse.
[0085] For example, as illustrated in FIG. 5B, in order to facilitate the
air discharged
from the cooler 3 to flow toward the muffler 4, the baffle 15 includes a
plurality of holes 150,
for example, the holes can be circular holes, oblong holes and other
structural forms, and the
shapes of the holes can be arranged as required, which is not limited here.
The baffle
illustrated in FIG. 5B will be described by taking the hole 150 as a round
hole as an example.
For example, the air discharged from the cooler 3 can flow toward the muffler
4 through
holes in the baffle 15. Referring to FIG. 3A, FIG. 4, and FIG. 5A, the cooler
3 includes an air
outlet side and an air inlet side, which are oppositely arranged. As
illustrated in FIG. 3A, the
upper side of the cooler 3 is the air outlet side and the lower side of the
cooler 3 is the air inlet
side. As illustrated in FIG. 4 and FIG. 5A, the left side of cooler 3 is the
air outlet side, and
the right side of cooler 3 is the air inlet side. For example, air enters from
the air inlet side of
the cooler 3 and is discharged from the air outlet side of the cooler 3.
[0086] For example, referring to FIG. 5A, FIG. SC and FIG. 5D, an interval
is
provided between the cooler 3 and the muffler 4, and one side SO of the cooler
3 that exhausts
air faces the muffler 4. One side (air outlet side) SO of the cooler 3 that
exhausts air is
illustrated in figs. 3A, 3B, 4, 5A and 5C.

Date Recue/Date Received 2022-01-05
[0087] For example, referring to FIG. 5B, the baffle 15 includes a
plurality of holes
150, and referring to FIG. 5C, the distance D1 between the baffle 15 and the
muffler 4 is less
than the distance D2 between the baffle 15 and the cooler 3.
[0088] For example, as illustrated in FIG. 5C and FIG. 5D, the muffler 4
includes a
first side Si, a second side S2, and a third side S3, the first side Si faces
the cooler 3, the
second side S2 and the third side S3 are connected with the first side Si,
respectively, and the
baffle 15 is at least located outside the first side S1 of the muffler 4 to
separate the exposed
high-temperature part of the muffler 4 from external components.
[0089] As illustrated in FIG. 5C, the baffle 15 is located outside the
first side Si, the
second side S2, and the third side S3 of the muffler 4. Therefore, the exposed
high-temperature part of the muffler 4 is separated from external components,
and the
influence of the muffler 4 on external components such as the cooler 3 can be
reduced. For
example, external components include, but are not limited to, the cooler 3.
FIG. 5C is
described with reference to the case where the second side S2 and the third
side S3 are
provided with the baffle 15, and the length of a part of the baffle 15 outside
the second side
S2 in the first direction X is larger than that of the second side S2 in the
first direction X, and
the length of a part of the baffle 15 outside the third side S3 in the first
direction X is greater
than that of the third side S3 in the first direction X, by way of example. In
other
embodiments, the part of the baffle 15 outside the second side S2 can also
have other lengths
in the first direction X, and the part of the baffle 15 outside the third side
S3 can also have
other lengths in the first direction X.
[0090] For example, in the embodiment of the present disclosure, the second
direction
Y intersects with the first direction X. Further, the second direction Y is
perpendicular to the
first direction X. For example, the second direction Y and the first direction
X are directions
parallel with the supporting surface of the carrier. For example, the
supporting surface of the
carrier is the surface on which various components are placed.
[0091] It should be noted that the arrangement position of the baffle 15 is
not limited
to the case illustrated in FIG. 5C. As illustrated in FIG. 5D, the baffle 15
may be provided
only outside the first side Si of the muffler 4.

Date Recue/Date Received 2022-01-05
[0092] As illustrated in FIG. 5C and FIG. 5D, the second side S2 and the
third side S3
are oppositely arranged.
[0093] As illustrated in FIG. 5C and FIG. 5D, the muffler 4 includes a
fourth side S4,
which is arranged opposite to the first side Si. For example, the muffler 4 is
connected with
the exhaust pipe 9 at the fourth side S4.
[0094] As illustrated in FIG. 5D, the muffler 4, the baffle 15, and the
cooler 3 are
sequentially arranged in the first direction X. In some embodiments, in order
to better reduce
the heat radiation, the size of the baffle 15 in the second direction Y is
greater than that of the
muffler 4 in the second direction Y, and is greater than that of the cooler 3
in the second
direction Y. As illustrated in FIG. 5C, the size of a part of the baffle 15
outside the first side
Si of the muffler 4 in the second direction Y is greater than that of the
muffler 4 in the second
direction Y, and is greater than that of the cooler 3 in the second direction
Y.
[0095] For example, the baffle 15 can be made of metal material, but it is
not limited
to this, and those skilled in the art can choose suitable materials as needed.
In some
embodiments, the baffle 15 may comprise a steel plate.
[0096] In an embodiment of the present disclosure, referring to FIG. 1A,
FIG. 3A to
FIG. 5A, the muffler 4 may include a first part 41 and a second part 42, and
the first part 41
intersects with the second part 42, for example, the first part 41 is
perpendicular to the second
part 42. For example, the muffler 4 is L-shaped. For example, the side of the
muffler 4 may
refer to the side of the first part 41 of the muffler. For example, the bottom
surface of the first
portion 41 of the muffler 4 is located on the vehicle body 100. Of course, in
other
embodiments, the side surface of the muffler 4 may also refer to the side
surface of the whole
muffler 4. In this case, the side surface of the muffler 4 may refer to the
part of the muffler 4
that is not parallel with the supporting surface of the vehicle body 100.
[0097] It should be noted that the fracturing apparatus lb, the fracturing

example, the turbine fracturing auxiliary unit uses the electric motor as the
power source to
drive the lubricating, cooling, turbine engine starting, air supply,
ventilating part and other
components of the whole machine.
[00101] For example, in the embodiment of the present disclosure, the
driving electric
motor being directly connected with the actuator refers to that there is no
hydraulic unit
between the driving electric motor and the actuator. For example, the
hydraulic unit includes
a hydraulic pump. For example, in the embodiment of the present disclosure,
the actuator is
an electric drive component instead of a hydraulic drive component.
[00102] At least one embodiment of the present disclosure provides a
fracturing
system including any fracturing apparatus as described above.
[00103] FIG. 7A illustrates a schematic diagram of a fracturing system
according to an
embodiment of the present disclosure, the fracturing system includes the
turbine fracturing
apparatus as described above, a manifold apparatus, a sand mixing apparatus, a
fracturing
fluid mixing apparatus, a sand conveying apparatus, and a sand silo, etc. For
example, the
sand silo is used to store a proppant which can be conveyed to the sand mixing
apparatus
through a conveying mechanism. For example, the chemical adding apparatus and
a clean
water source are coupled to the fracturing fluid mixing apparatus,
respectively, where
Date Recue/Date Received 2022-01-05
fracturing base fluid is formed. For example, the fracturing base fluid can be
then conveyed
into the sand mixing apparatus to be fully mixed with the proppant, so as to
form fracturing
fluid which can be conveyed into the turbine fracturing apparatus via the
manifold apparatus.
For example, the turbine fracturing apparatus raises the pressure of the
fracturing fluid sucked
in at low pressure and drains it away to a wellhead at high-pressure.
[00104] For example, at least one of the chemical adding apparatus, the
sand mixing
apparatus, the sand conveying apparatus, and the fracturing fluid mixing
apparatus is
powered by the power supply. A measuring apparatus which can be vehicle-
mounted,
semi-trailer-mounted or skid-mounted may control the turbine fracturing
apparatus, the
turbine generating apparatus, the power supply 12, the manifold apparatus, the
sand mixing
apparatus, the fracturing fluid mixing apparatus, the sand conveying
apparatus, and the sand
silo, thus realizing the centralized control of the turbine-electric driven
well site.
[00105] For example, referring to FIG. 6, the power supply 12 can be
electrically
connected with a switch cabinet and a transformer substation successively, so
as to provide
electric power to the electric motors of the sand conveying apparatus, the
sand mixing
apparatus, the fracturing fluid mixing apparatus, and the auxiliary unit of
the turbine
fracturing apparatus.
[00106] FIG. 7B illustrates a fracturing system provided by an embodiment
of the
present disclosure. For example, as illustrated in FIG. 7B, the plunger pump
of at least one
fracturing apparatus is detachably provided, and the plunger pump can be
substituted by an
electric generator to form at least a part of the power supply 12. To solve
the problem of
electricity consumption at the well site, a structure for quick-replacement
illustrated in FIG. 8
and FIG. 9 is provided, such that the turbine fracturing apparatus can be
changed into a
turbine generating apparatus quickly. This can be done by replacing the
plunger pump with an
electric generator.
[00107] As illustrated in FIG. 7A and FIG. 7B, the solid line refers to
preparing
fracturing fluid and the running direction of the fracturing fluid; the dotted
line refers to cable
control.
[00108] As illustrated in FIG. 8, the first base 201 is provided with a
first forklift slot
202 to facilitate the replacement of the plunger pump. The plunger pump 1 and
the first base
26
Date Recue/Date Received 2022-01-05
201 are mounted as a whole. The replacement can be performed by removing the
fixing bolts
between the first base 201 and the vehicle body 100 and then extending a fork
of the forklift
into the first forklift slot when the plunger pump needs to be replaced.
1001091 As illustrated in FIG. 9, likewise, the structure for quick-
replacement of the
electric generator substantially includes an electric generator 303, a second
base 301, and a
second forklift slot 302. When the turbine fracturing apparatus needs to be
changed into the
electric generator apparatus, it is only necessary to remove the plunger pump
and then mount
the electric generator apparatus quickly to realize the quick replacement from
fracturing
operation to power generation operation. The reducer coupled to the turbine
engine can be set
to a predetermined rotate speed to slow down the rotate speed of the turbine
engine to a
certain range, which can not only meet the requirements of the plunger pump
operation, but
also drive the generator for power generation. An output cable can be quickly
coupled to the
control system of the turbine fracturing apparatus, the sand mixing apparatus,
the fracturing
fluid mixing apparatus, and the sand conveying apparatus via a quick
connector.
1001101 For example, the turbine generating apparatus adopts the form of
one backup
and one use to ensure the safety of power supply. Any two turbine fracturing
apparatuses in
the well site can be used as power supply 12 in the way of replacing the
plunger pump
quickly with an electric generator through the structure for quick-
replacement. In another
embodiment, the two mounted turbine generating apparatuses are preferably
arranged on both
sides of the manifold apparatus to facilitate cable connection. In another
embodiment, the two
mounted turbine generating apparatuses are preferably arranged symmetrically
about the
center line of the manifold apparatus, such that the cable laying is more
convenient.
1001111 It should be noted that the fracturing apparatus provided by the
embodiment of
the present disclosure may not adopt the structure of adjusting the
installation positions of the
cooler or adjusting the installation positions of the cooler and muffler as
illustrated in FIG.
3A, FIG. 4 and FIG. 5A. That is, in the fracturing apparatus provided by some
embodiments
of the present disclosure, the cooler may not be arranged above the plunger
pump 1, and in
the fracturing apparatus provided by some embodiments of the present
disclosure, the cooler
may not be arranged opposite to the muffler 4. That is, in the fracturing
apparatus according
to some embodiments of the disclosure, the cooler can be arranged in other
ways.

[00112] In the case of no conflict, the features in the same embodiment and
different
embodiments of the present disclosure can be combined with each other.
[00113] What have been described above are only specific implementations of
the
present disclosure, the protection scope of the present disclosure is not
limited thereto. Any
changes or substitutions easily occur to those skilled in the art within the
technical scope of
the present disclosure should be covered in the protection scope of the
present disclosure.
Therefore, the protection scope of the present disclosure should be based on
the protection
scope of the claims.
