Title (EN) LINER HANGER
(FR) SUSPENSION DE COLONNE PERDUE
Abstract:
(EN) Liner hanger to be placed in an existing casing with a flexible expansion seal (180) and a metallic gripping element (190) disposed on inclined surfaces such that they are moved radially when a leadscrew nut (130) is moved axially relative to an inner, hollow shaft (150). The lead screw nut is moved axially when a lead screw is rotated therein, and the lead screw is rotatably disposed around the inner, hollow shaft (150).
(FR) L'invention porte sur une suspension de colonne perdue destinée à être disposée dans un tubage existant avec un joint d'étanchéité à dilatation souple (180) et un élément de saisie métallique (190) disposés sur des surfaces inclinées de telle sorte qu'ils sont déplacés radialement lorsqu'un écrou pour vis sans fin (130) est déplacé axialement par rapport à un arbre creux interne (150). L'écrou pour vis sans fin est déplacé axialement lorsqu'une vis sans fin est amenée à tourner à l'intérieur de celui-ci, et la vis sans fin est disposée à rotation autour de l'arbre creux interne (150).
