Title
(EN) DOWNHOLE TUBULAR SYSTEM, DOWNHOLE TUBULAR AND METHOD OF FORMING A CONTROL LINE PASSAGEWAY AT A TUBULAR
(FR) SYSTÈME TUBULAIRE DE FOND DE TROU, ÉLÉMENT TUBULAIRE DE FOND DE TROU ET PROCÉDÉ DE FORMATION D'UN PASSAGE DE LIGNE DE COMMANDE AU NIVEAU D'UN ÉLÉMENT TUBULAIRE
Abstract
(EN) A downhole tubular system including a tubular defining a wall having an inner radial surface and an outer radial surface, the outer radial surface having a circumferential channel formed therein extending 360 degrees defining a punch portion, the inner radial surface defining an inner bore; a sleeve attachable around the tubular; and at least a portion of a control fluid chamber passageway defined between the sleeve and the outer radial surface, the wall occluding fluidic communication between the control line passageway and the inner bore until the punch portion has been punctured.
(FR) Système tubulaire de fond de trou comprenant un élément tubulaire définissant une paroi ayant une surface radiale interne et une surface radiale externe, la surface radiale externe ayant un canal circonférentiel formé à l'intérieur de celle-ci s'étendant sur 360 degrés définissant une partie de poinçon, la surface radiale interne définissant un alésage interne ; un manchon pouvant être fixé autour de l'élément tubulaire ; et au moins une partie d'un passage de chambre de fluide de commande défini entre le manchon et la surface radiale externe, la paroi occluant la communication fluidique entre le passage de ligne de commande et l'alésage interne jusqu'à ce que la partie de poinçon ait été perforée.
