GAS SOURCE SYSTEM FOR SUPPLYING GAS TO A TURBINE
ENGINE BY FRACTURING MANIFOLD EQUIPMENT
TECHNICAL FIELD
The present invention relates to the technical field of turbine fracturing,
and
particularly relates to a gas source system for supplying gas to a turbine
engine by
fracturing manifold equipment.
BACKGROUND
For recent decades, hydraulic fracturing has been used to increase the
production in oil
or gas wells. In this process, a fracturing pump is used to pump the fluid
into a wellbore
under high pressure, then the fluid is squeezed into the formation, fracturing
several
hydraulic fractures. Water, other liquids as well as fracturing proppants are
also injected
into the fractures. After fracturing, the fracturing base fluid is returned to
the ground, with
the fracturing proppants remaining in the fractures to prevent fracture
closure, through
which a large amount of oil and gas enter the wellbore to be exploited.
In the working sites of fracturing in oil and gas fields all over the world,
the gas source
supply for turbine fracturing is as follows:
The turbine fracturing trucks are arranged side by side, gas pipelines are
connected
between the turbine fracturing trucks, gas filters are disposed at the
position of accessories
of the turbine fracturing trucks, and the whole gas piping is arranged around
the vehile set.
The problems are as follows:
1. Unsafety: The gas filters are disposed at the rear of the turbine
fracturing trucks,
which is a high pressure region, with a risk of damaging the filters;
moreover, the
protection of most gas filters is not safe enough, once the high-pressure
pipeline leaks, the
gas supply will be disconnected, finally affecting the efficiency of the
wellsite.
2. Unreasonable arrangement: The gas pipeline for the whole vehile set is in
an
annular form, if one of turbine fracturing trucks has to drive away, the
piping for the whole
vehile set would be broken, with a risk of cutting off the gas, thus affecting
the efficiency
of the wellsite.
3. Incompact structure, labor and time-consuming of installation: It is
necessary to
temporarily install gas filters, gas pipelines and other materials after the
wellsite
arrangement has been completed, increasing the difficulty of wellsite
installation and

affecting the operating efficiency.
