Title (EN) DOWNHOLE TOOL WITH MULTIPLE PISTONS
(FR) OUTIL EN PROFONDEUR DE TROU À PISTONS MULTIPLES
Abstract:
(EN) A downhole tool includes a tool body comprising an inner housing and an outer housing to form an annulus between the inner housing and the outer housing and a primary piston positioned within the annulus to form a primary cavity within the annulus. The downhole tool further includes a backup piston positioned within the annulus to form a second cavity within the annulus and a pressure operating device in fluid communication with the annulus.
(FR) La présente invention concerne un outil en profondeur de trou qui comprend un corps d'outil, qui comprend un logement intérieur et un logement extérieur pour former un espace annulaire entre le logement intérieur et le logement extérieur, et un piston principal positionné à l'intérieur de l'espace annulaire pour former une cavité principale à l'intérieur de l'espace annulaire. L'outil en profondeur de trou comprend en outre un piston de secours positionné à l'intérieur de l'espace annulaire pour former une seconde cavité à l'intérieur de l'espace annulaire et un dispositif d'actionnement à pression en communication fluidique avec l'espace annulaire.
