Title
(EN) MECHANISM FOR ANCHORING A WELL TOOL
(FR) MECANISME D'ANCRAGE D'UN INSTRUMENT DE PUITS
Abstract
(EN)
A longitudinally compact mechanism for anchoring a well tool to a casing includes a plurality of first slip members (70) and a plurality of second slip members (100). The first slip members (70) and the second slip members (100) are carried on the well tool at the approximate same longitudinal position, and the first slip members are alternately radially positioned with the second slip members. Each slip member is expanded by relative movement of an independent piston (63, 88) operatively connected thereto.
(FR)
La présente invention concerne un mécanisme compact d'ancrage d'un instrument de puits au tubage de ce dernier, comprenant une première série d'éléments de glissement (70) et une seconde série d'éléments de glissement (100), la position desdits éléments (70, 100) sur l'instrument est à peu près la même dans le sens longitudinal, et les premiers éléments de glissement sont disposés dans des positions radiales alternées avec celles des seconds éléments de glissement. Chaque élément de glissement est extensible sous l'effet du mouvement relatif d'un piston indépendant (63, 88) qui fonctionne en liaison avec l'élément de glissement respectif.
