Title (EN) EXTENDABLE PERFORATION IN CASED HOLE COMPLETION
(FR) PERFORATION EXTENSIBLE DANS UNE COMPLÉTION TUBÉE
Abstract:
(EN) System and methods for providing a fluid flow path through a lower casing (20) and a cement of a subterranean well (10) includes a plurality of perforation tubes (26) extending through a sidewall of a lower casing, the perforation tubes moveable from a retracted position to an extended position. In the retracted position a minor length (30) of the perforation tubes is located outside of an outer diameter surface of the lower casing. In the extended position, a major length (34) of the perforation tubes is located outside of the outer diameter surface of the lower casing, the major length being greater than the minor length. In the extended position, the perforation tubes extend radially outward from the outer diameter surface of the lower casing. Each of the plurality of perforation tubes is positioned axially along the lower casing to be moveable to an extended position in a formation zone (18) of the subterranean well.
(FR) L'invention concerne un système et des procédés pour fournir un trajet d'écoulement de fluide à travers un tubage inférieur (20) et un ciment d'un puits souterrain (10), qui comprennent une pluralité de tubes de perforation (26) s'étendant à travers une paroi latérale d'un tubage inférieur, les tubes de perforation pouvant être déplacés d'une position rétractée à une position étendue. Dans la position rétractée, une longueur mineure (30) des tubes de perforation est située à l'extérieur d'une surface de diamètre externe du tubage inférieur. Dans la position étendue, une longueur majeure (34) des tubes de perforation est située à l'extérieur de la surface de diamètre externe du tubage inférieur, la longueur majeure étant supérieure à la longueur mineure. Dans la position étendue, les tubes de perforation s'étendent radialement vers l'extérieur à partir de la surface de diamètre externe du tubage inférieur. Chacun de la pluralité de tubes de perforation est positionné de manière axiale le long du tubage inférieur pour pouvoir être déplacé vers une position étendue dans une zone de formation (18) du puits souterrain.
