Apparatus and method for penetrating cement (300) surrounding a tubular (200) cemented to a formation (400). The apparatus comprises a bore (10) through the tubular wall (200), and an intermediate fluid channel (102) in an insert (100) within the bore. An inner sleeve (120) may be disposed on the interior surface of the tubular wall (200). The inner sleeve (120) is movable between a closed position wherein fluid connection between the interior of the tubular and the bore is prevented, and an open position wherein fluid connection between the interior of the tubular and the bore is allowed. An abrasive and/or etching fluid is supplied through the channel (102) to remove cement and/or the insert (100) or piston assembly.
Un appareil et un procédé pour pénétrer le béton (300) entourant une tubulure (200) cimentée à une formation (400). Lappareil comprend un orifice (10) à travers la paroi de la tubulure (200) et un canal de fluide intermédiaire (102) dans un élément rapporté (100) à lintérieur de lorifice. Un manchon intérieur (120) peut être disposé sur la surface intérieure de la paroi de la tubulure (200). Le manchon intérieur (120) est mobile entre une position fermée à laquelle la communication fluidique entre lintérieur de la tubulure et lorifice est empêchée, et une position ouverte à laquelle la communication fluidique entre lintérieur de la tubulure et lalésage est permise. Un fluide abrasif ou un fluide de gravure est acheminé par le canal (102) pour retirer le béton ou lélément rapporté (100) ou lensemble piston.
