Abstract[English]
A wet mate-able downhole coupler comprises ae female coupler, and a male coupler. Typically, the female coupler is installed first as part of a well completion string, where later the male coupler with a string of tubulars connected to its lower end is landed into the female coupler. The female coupler is connected to one or several electric cables and/or hydraulic tubes placed outside the wellbore tubulars or as integrated components in the wellbore tubulars, where such lines are routed to the surface of the well, or the so-called Xmas tree. Between the female coupler and the Xmas tree there may be sensors and/or valves connected to said cables and/or hydraulic lines.[French]
Selon l'invention, un coupleur de fond de trou apte à un accouplement humide comprend un coupleur femelle et un coupleur mâle. Typiquement, le coupleur femelle est installé en premier dans le cadre d'une colonne de complétion de puits, et plus tard, le coupleur mâle doté d'un train d'éléments tubulaires relié à son extrémité inférieure étant posé dans le coupleur femelle. Le coupleur femelle est relié à un ou plusieurs câbles électriques et/ou tubes hydrauliques placés à l'extérieur des éléments tubulaires de puits de forage ou sous la forme de composants intégrés dans les éléments tubulaires de puits de forage, de telles conduites étant acheminées jusqu'à la surface du puits, ou au dénommé arbre de Noël. Entre le coupleur femelle et l'arbre de Noël, des capteurs et/ou des vannes peuvent être présents, reliés auxdits câbles et/ou conduites hydrauliques.
