Title (EN) FLUID INJECTION DEVICE
(FR) dispositif d'injection de fluide
Abstract: front page image
(EN)The present invention regards a device designed for injection of fluids in a well bore, typically an offshore well bore for petroleum production and gas injection / gas lift system for fluid injection. The device comprises a outer hollow housing (1) with an internal body (2) moveable within the outer housing (1) with an internal bore(3) which in a first closed position is closed with a metal to metal seal system between the outer housing (1) and the internal body (2), which internal body (2) is operated by pressure differential across the internal body (2), where the internal body (2) is designed with slots (4) forming outlets of the internal bore (3) which in an open position of the device is positioned outside of the outer housing (1).
(FR)La présente invention concerne un dispositif pour l'injection de fluides dans un puits de forage, en particulier un puits de forage en mer pour l'extraction de pétrole, et un système d'injection de gaz/ poussée de gaz pour l'injection de fluide. Le dispositif comprend un boîtier extérieur creux (1) comportant un corps intérieur (2) mobile avec un forage intérieur (3) obstrué par un système d'étanchéification métal sur métal dans une première position fermée entre le boîtier extérieur (1) et le corps intérieur (2), le corps intérieur (2) est actionné par pression différentielle, il est percé de fentes (4) formant des sorties pour le forage intérieur (3) qui est positionné à l'extérieur du boîtier extérieur (1) dans une position ouverte du dispositif.
