Title (EN) DOWNHOLE FLOW CONTROL DEVICE
(FR) DISPOSITIF DE RÉGULATION DU DÉBIT DE FOND DE TROU
Abstract:
(EN) A downhole flow control device (22) comprises a tubular member (28) to be located within a well bore and having a flow port (24) formed through a wail thereof to provide fluid communication with the wellbore. The flow control device (22) further comprises a blocking arrangement (32) mounted in proximity to the flow port (24) and comprising a swellable material configured to swell upon exposure to a triggering fluid, wherein in an unswollen state the blocking arrangement (32) does not Interfere with the flow port (24) such that flow through the flow port is unrestricted by the blocking arrangement, and in a swollen state the blocking arrangement encroaches over the flow port to restrict flow therethrough.
(FR) L'invention a trait à un dispositif de régulation du débit de fond de trou (22) qui comprend un élément tubulaire (28) devant se trouver à l'intérieur d'un trou de forage et présentant un orifice d'écoulement (24) pratiqué dans une paroi de cet élément afin d'assurer une communication fluidique avec le trou de forage. Le dispositif de régulation du débit (22) comporte en outre un agencement de blocage (32) monté à proximité de l'orifice d'écoulement (24) et comprenant un matériau capable de gonfler qui est conçu pour gonfler lorsqu'il est exposé à un fluide déclencheur. A l'état non gonflé, l'agencement de blocage (32) n'empiète pas sur l'orifice d'écoulement (24) de sorte que l'écoulement par ledit orifice d'écoulement n'est pas limité par l'agencement de blocage, et, à l'état gonflé, cet agencement de blocage dépasse de l'orifice d'écoulement afin de limiter l'écoulement par ledit orifice.
