Title
(EN) DOWNHOLE FLOW CONTROL APPARATUS
(FR) APPAREIL DE RÉGULATION D'ÉCOULEMENT EN FOND DE TROU
Abstract
(EN)
There is provided a downhole flow control apparatus comprising: a housing; a port extending through the housing; a passage disposed within the housing for conducting material to and from the port; a flow control member displaceable relative to the port; and a flow control member actuator configured for producing a pressurized fluid for urging the displacement of the flow control member.
(FR)
L'invention concerne un appareil de régulation d'écoulement en fond de trou, comprenant : un boîtier ; un orifice s'étendant à travers le boîtier ; un passage disposé à l'intérieur du boîtier pour acheminer du matériau vers et à partir de l'orifice ; un élément de régulation d'écoulement apte à être déplacé par rapport à l'orifice ; et un actionneur d'élément de régulation d'écoulement configuré pour produire un fluide pressurisé pour provoquer le déplacement de l'élément de régulation d'écoulement.
