Title
(EN) TUBING HANGER WITH SHIFTABLE ANNULUS SEAL
(FR) DISPOSITIF DE SUSPENSION DE TUBE AVEC JOINT ANNULAIRE DÉPLAÇABLE
Abstract
(EN)
A tubing: hanger assembly with a shiftable annulus seal is provided. The shiftable annulus seal allows for selectively sealing the tubing hanger within a easing hanger, a wellhead, or a tubing head. The tubing hanger assembly also includes a secondary annulus flow path formed through the body of the tubing hanger. The shiftable annulus seal selectively opens/closes a relatively large flow path to the tubing string annulus for circulation of fluid through the tubing string and setting a -packer. The secondary annulus flow path facilitates monitoring and bleeding of pressure· front the annulus after the shiftable annulus seal is closed.

L'invention concerne un ensemble dispositif de suspension de tube comprenant un joint annulaire déplaçable. Le joint annulaire déplaçable permet de sceller de manière sélective le dispositif de suspension de tube à l'intérieur d'un support de suspension de facilitation, d'une tête de puits ou d'une tête de colonne de production. L'ensemble dispositif de suspension de tube comprend également un trajet d'écoulement annulaire secondaire formé à travers le corps du dispositif de suspension de tube. Le joint annulaire déplaçable ouvre/ferme de manière sélective un trajet d'écoulement relativement large vers l'espace annulaire de colonne de production pour permettre la circulation d'un fluide à travers la colonne de production et pour fixer une garniture d'étanchéité. Le trajet d'écoulement annulaire secondaire facilite la surveillance et la purge de la pression provenant de l'espace annulaire après fermeture du joint annulaire déplaçable.
