Title (EN) FULLY ELECTRIC TOOL FOR CONTINOUS DOWNHOLE FLOW CONTROL
(FR) OUTIL ENTIÈREMENT ÉLECTRIQUE POUR RÉGULATION CONTINUE DU DÉBIT EN FOND DE TROU
Abstract:
(EN) A fully electric tool for continuous downhole flow control is described, said tool (100) comprising a body (101) and along the said body (101), actuating set(s), each actuating set comprising a passage system (102) comprised of shaft(s) (108) radially disposed along said cylindrical body (101), each of said shaft (s)(108) being actuated with its opposed pair or in an independent way in a well-defined position or not, said shaft(s) (108) being provided of spherical element(s)or sphere(s) (124), provided of at least one window (125) forming piles of sphere(s) (124) in shaft(s) (108), the rotation of said shaft(s)(108) of piles of sphere(s) (124) enabling the opening or total or partial obstruction of holes (111) by the total or partial coincidence of said window(s) (125) of sphere(s)(124) with said bore(s) (111) of said cylindrical body (101).
(FR) L'invention concerne un outil entièrement électrique pour régulation continue du débit en fond de trou, ledit outil (100) comportant un corps (101) et, le long dudit corps (101), un ou des ensembles d'actionnement, chaque ensemble d'actionnement comportant un système (102) de passages constitué d'un ou plusieurs axes (108) disposés radialement le long dudit corps (101) cylindrique, chacun desdits axes (108) étant actionné avec la paire qui lui est opposée ou de manière indépendante dans une position bien définie ou non, ledit ou lesdits axes (108) étant munis d'un ou plusieurs éléments sphériques ou sphères (124), munis d'au moins une fenêtre (125) formant des piles de sphères (124) dans l'axe ou les axes (108), la rotation dudit ou desdits axes(108) de piles de sphères (124) permettant l'ouverture ou l'obstruction totale ou partielle de trous (111) par la coïncidence totale ou partielle de ladite ou desdites fenêtres (125) de sphères (124) avec ledit ou lesdits alésages (111) dudit corps (101) cylindrique.
