Title
(EN) TEMPERATURE RESPONSIVE PACKER AND ASSOCIATED HYDROCARBON PRODUCTION SYSTEM
(FR) GARNITURE D'ÉTANCHÉITÉ RÉAGISSANT À LA TEMPÉRATURE ET SYSTÈME DE PRODUCTION D'HYDROCARBURES ASSOCIÉ
Abstract
(EN)
The present invention relates to a hydrocarbon production system (10). The hydrocarbon production system comprises: a pipe (18) placeable in a hole or wellbore (16), wherein an annulus (30) is defined between the pipe and the hole or wellbore; and at least one ring-shaped packer (22) provided around the pipe, wherein the packer comprises at least one fluid- filled bellows or pocket (24) which is adapted to reversibly expand when externally subjected to increased temperature, such that the annulus (30) is restricted. The present invention also relates to a packer (22), and a method of restricting the annulus (30) between a production or injector pipe (18) and a hole or wellbore (16).
(FR)
La présente invention porte sur un système de production d'hydrocarbures (10). Le système de production d'hydrocarbures comprend : un tuyau (18) pouvant être disposé dans un trou ou puits de forage (16), un anneau (30) étant défini entre le tuyau et le trou ou le puits de forage ; et au moins une garniture d'étanchéité de forme annulaire (22) étant disposée autour du tuyau, la garniture d'étanchéité comprenant au moins une poche ou un soufflet rempli de fluide (24) qui est apte à se dilater de façon réversible quand il est soumis extérieurement à une température accrue, de telle sorte que l'anneau (30) est restreint. La présente invention porte également sur une garniture d'étanchéité (22), et sur un procédé de restriction de l'anneau (30) entre un tuyau de production ou d'injecteur (18) et un trou ou un puits de forage (16).
