Title
(EN) COMPLETION ISOLATION SYSTEM WITH TUBING MOVEMENT COMPENSATOR
(FR) SYSTÈME D'ISOLATION DE COMPLÉTION AYANT UN COMPENSATEUR DE MOUVEMENT DE TUBE
Abstract
(EN) A system includes a tubular disposed within a borehole, a sleeve disposed around the tubular, and an isolation element bounded to an outer diameter of the sleeve. The inner diameter of the sleeve is connected to an outer diameter of the tubular via a plurality of seals. The isolation element is configured to conform to a surface of the borehole when the isolation element is in an expanded configuration. The sleeve compensates for movement of the tubular by being able to freely move across the tubular.
(FR) La présente invention concerne un système qui comprend un élément tubulaire disposé à l'intérieur d'un trou de forage, un manchon disposé autour de l'élément tubulaire, et un élément d'isolation lié à un diamètre externe du manchon. Le diamètre interne du manchon est relié à un diamètre externe de l'élément tubulaire par le biais d'une pluralité de joints d'étanchéité. L'élément d'isolation est configuré pour se conformer à une surface du trou de forage lorsque l'élément d'isolation se trouve dans une configuration étendue. Le manchon compense le mouvement de l'élément tubulaire en étant capable de se déplacer librement à travers l'élément tubulaire.
