Title (EN) STAGE CEMENTING TOOL AND METHOD
(FR) OUTIL ET PROCÉDÉ DE CIMENTATION D’ÉTAGE
Abstract:
(EN) A well tool (200) for use in completing a wellbore includes a tubular housing (210) having a central bore (204) and a housing port (218) through a wall of the tubular housing, an inner mandrel (212) disposed within the tubular housing and selectively movable between a first, closed position and a second, open position in response to a fluid pressure in the central bore, a sealing element (214) circumscribing a portion of the tubular housing, and a setting sleeve (216). The inner mandrel (212) is configured to open the housing port (218) when the inner mandrel is in the second, open position. The setting sleeve (216) is movable between a first, retracted position and a second, expanded position, where the setting sleeve is configured to activate the sealing element (214) in the second, expanded position in response to movement of the inner mandrel to the second, open position.
(FR) La présente invention concerne un outil de puits (200) pour utilisation dans la formation d’un puits de forage qui comprend un boîtier tubulaire (210) comportant un alésage central (204) et un orifice de boîtier (218) à travers une paroi du boîtier tubulaire, un mandrin interne (212) disposé à l’intérieur du boîtier tubulaire est sélectivement déplaçable entre une première position fermée et une deuxième position ouverte en réponse à une pression de fluide dans l’alésage central, un élément d’étanchéité (214) entourant une partie du boîtier tubulaire, et un manchon de réglage (216). Le mandrin interne (212) est configuré pour ouvrir l’orifice de boîtier (218) lorsque le mandrin interne est dans la deuxième position ouverte. Le manchon de réglage (216) est déplaçable entre une première position rétractée et une deuxième position déployée, le manchon de réglage étant configuré pour activer l’élément d’étanchéité (114) dans la deuxième position déployée en réponse au déplacement du mandrin interne vers la deuxième position ouverte.
