CA 2577897

A packer (30) includes one or more anchors (36, 38) for securing the packer in a wellbore and a pair of seal elements (34, 40) that form a fluid seal. The packer assembly is hydraulically set (41) and, thus, it can be located at any desired position within the wellbore, i.e. not necessarily immediately atop the liner hanger. The packer assembly is secured within the wellbore by a staged setting process through use of shear pins (60) that have increasingly stepped shear values. Redundancy in packer sealing is provided by the use of two seal elements to establish fluid sealing. The design of the packer assembly also provides hydraulic isolation of the actuating portions of the packer assembly upon setting and maybe used for a tie back string.

La présente invention concerne une remblayeuse (30), ladite remblayeuse comprenant une ou plusieurs ancre(s) (36, 38) destinée(s) à fixer la remblayeuse dans un forage et deux éléments d~obturation (34, 40) formant un barrage aux fluides. L~assemblage de la remblayeuse est installé hydrauliquement (41) et peut être ainsi situé à quelque endroit désiré que ce soit dans le forage, c~est-à-dire pas nécessairement au sommet du liner. L~assemblage de la remblayeuse est fixé dans le forage par un procédé d~installation étagée au moyen de goupilles de cisaillement (60) qui ont des valeurs de cisaillement échelonnées allant en augmentant. La redondance de l~obturation de la remblayeuse est fournie par l~emploi de deux éléments d~obturation servant à établir l~obturation des fluides. La conception de l~assemblage de la remblayeuse fournit également l~isolation hydraulique des parties de l~actionneur de l~assemblage de la remblayeuse lors de l~installation et peut être employée pour une bride d~ancrage.
