Title (EN) DEVICE FOR A DOWN-HOLE ASSEMBLY
(FR) DISPOSITIF POUR ENSEMBLE DE FOND DE PUITS
Abstract:
(EN) A wireline conveyable device for a fluid operable borehole tubing assembly comprising a tubular body having a first end intended to form the upper end when in the borehole and a second open end intended to form the lower end. The tubular body includes at least one aperture in a wall thereof to facilitate passage of fluid through the tubular body. Electrically actuable outwardly moving anchoring means are attached to the tubular body for positively locating the tubular member at a predetermined position within the borehole tubing, in use. An electrically actuable sealing means attached to the tubular body and arranged, in use, for selectively sealing the space between the borehole tubing and the tubular body to divert fluid through the tubular body to bypass the sealing means for driving fluid actuable means located adjacent said second lower end of the tubular body.
(FR) Dispositif transportable par le câble de forage et destiné à un ensemble hydraulique à colonne de production dans le puits. Le dispositif comporte un corps tubulaire dont une première extrémité est destinée à former l'extrémité supérieure dans le puits et dont une seconde extrémité ouverte est destinée à former l'extrémité inférieure. Une paroi du corps tubulaire comprend au moins une ouverture facilitant le passage d'un fluide à travers ledit corps tubulaire. Des éléments électriques d'ancrage déplaçables vers l'extérieur sont fixés au corps tubulaire pour positionner de manière positive l'élément tubulaire dans une position prédéterminée à l'intérieur de la colonne de production du puits. Un obturateur électrique est fixé au corps tubulaire et adapté pour obturer de manière sélective l'espace compris entre ladite colonne de production et le corps tubulaire afin de détourner le fluide dans le corps tubulaire de sorte qu'il contourne l'obturateur pour un dispositif à entraînement hydraulique situé à proximité de ladite seconde extrémité inférieure dudit corps tubulaire.
