Title (EN) APPARATUS FOR INJECTING A FLUID INTO A GEOLOGICAL FORMATION
(FR) APPAREIL POUR INJECTER UN FLUIDE DANS UNE FORMATION GÉOLOGIQUE
Abstract:
(EN) An apparatus (1) for injecting a fluid into a geological formation (10) comprises, in sequence from a string supplying an injection fluid from the surface, an upstream packer (200), a normally open sleeve valve (100), a downstream packer (300) and a normally open bottom valve (400). As the pressure within a central bore (2) increases, the bottom valve (400) blocks axial flow. As the bore pressure continues to increase, the packers (200, 300) are set, and then the sleeve valve (100) opens for injection.
(FR) La présente invention concerne un appareil (1) pour injecter un fluide dans une formation géologique (10) qui comprend, en séquence à partir d'une chaîne alimentant un fluide d'injection depuis la surface, une garniture d'étanchéité en amont (200), une vanne à manchon normalement ouverte (100), une garniture d'étanchéité en aval (300) et une vanne inférieure normalement ouverte (400). Lorsque la pression à l'intérieur d'un alésage central (2) augmente, la vanne inférieure (400) bloque l'écoulement axial. Lorsque la pression de forage continue à augmenter, les garnitures d'étanchéité (200, 300) sont installées, et ensuite la vanne à manchon s'ouvre (100) pour injection.+-
