Title (EN) REMOVABLE CONTROL LINE BARRIER
(FR) BARRIÈRE DE CONDUITE DE COMMANDE AMOVIBLE
Abstract:
(EN) A hydraulically operated downhole tool located at a depth where control line hydrostatic pressure would normally set the tool is temporarily isolated from hydrostatic pressure and changes thereto from well exposure or downhole operations until properly located. A removable barrier is placed in the control line to the tool at a height from the tool that limits the hydrostatic force exposed to the actuation mechanism for the tool. The preferred barrier is a rupture disc that is selectively broken with applied pressure from a remote location, typically the surface above the well. The mounting depth of the barrier can be varied to control the maximum hydrostatic pressure seen by the tool as it is advanced to the intended position.
(FR) Selon l'invention, un outil de fond de trou actionné hydrauliquement situé à une profondeur où la pression hydrostatique de la conduite de commande installerait normalement l'outil est temporairement isolé de la pression hydrostatique et de changements de cette dernière provenant de l'exposition au puits ou d'opérations de fond de trou jusqu'à ce qu'il soit correctement situé. Une barrière amovible est placée dans la conduite de commande vers l'outil à une hauteur par rapport à l'outil qui limite la force hydrostatique à laquelle le mécanisme d'actionnement de l'outil est exposé. La barrière préférée est un disque de rupture qui est rompu sélectivement avec une pression appliquée à partir d'un emplacement lointain, généralement la surface au-dessus du puits. La profondeur de montage de la barrière peut être amenée à varier pour commander la pression hydrostatique maximale subie par l'outil lorsqu'il est amené à avancer vers la position voulue.
