Title (EN) RECLOSABLE MULTI-ZONE ISOLATION USING A PISTON ASSEMBLY HAVING A LOCK OUT FEATURE
(FR) ISOLATION MULTI-ZONE REFERMABLE UTILISANT UN ENSEMBLE PISTON AYANT UN ÉLÉMENT DE VERROUILLAGE
Abstract:
(EN) A reclosable multi-zone isolation tool including a piston assembly with a lock out feature. The tool has an outer and inner tubular having an annular flow path defined there between, and a central flow path defined by the inner tubular. The annular flow path is in fluid communication with the first zone, while the central flow path is in fluid communication with the second zone. A sleeve is positioned in the annular flow path and axially moveable between an open and closed position. A mandrel is positioned within the inner tubular and coupled to the sleeve to actuate the sleeve between the open and closed position. A pressure responsive piston assembly is coupled to the mandrel in order to actuate the sleeve to the open position. Once in the open position, the piston assembly is "locked out," thereby allowing the mandrel and sleeve to move relative to the piston between the open and closed positions.
(FR) L'invention concerne un outil d'isolation multi-zone refermable, qui comprend un ensemble piston ayant un élément de verrouillage. L'outil comporte des éléments tubulaires externe et interne ayant un circuit d'écoulement annulaire défini entre eux, et un circuit d'écoulement central défini par l'élément tubulaire interne. Le circuit d'écoulement annulaire est en communication fluidique avec la première zone, tandis que le circuit d'écoulement central est en communication fluidique avec la seconde zone. Un manchon est positionné dans le circuit d'écoulement annulaire et est mobile axialement entre une position ouverte et une position fermée. Un mandrin est positionné dans l'élément tubulaire interne et couplé au manchon pour actionner le manchon entre la position ouverte et la position fermée. Un ensemble piston sensible à la pression est couplé au mandrin afin d'actionner le manchon vers la position ouverte. Une fois en position ouverte, l'ensemble piston est "verrouillé", en permettant ainsi au mandrin et au manchon de se déplacer par rapport au piston entre les positions ouverte et fermée.
