Title (EN) METHOD AND APPARATUS FOR CONTROLLING DOWNHOLE WATER PRODUCTION
(FR) PROCÉDÉ ET APPAREIL POUR COMMANDER LA PRODUCTION D'EAU EN PROFONDEUR DE FORAGE
Abstract:
(EN) An apparatus (10) for controlling water production in a wellbore (B) comprises a body in the form of a base pipe (12), the base pipe (12) having an axial flow passage in the form of axial throughbore (14) and a lateral flow passage in the form of radial port (16). A shroud (18) is disposed around the base pipe (12) and forms a housing of the apparatus (10). In use, the apparatus (10) forms part of a completion string (CS) for location in the wellbore (B), the apparatus (10) configured to direct production fluid into a production conduit (P) for recovery to surface (S), perform a quantitative measurement of water content within the production fluid, and vary the fluid flow in the fluid flow path based on the quantitative measurement of water content within the production fluid to maintain water production at or below a predetermined threshold.
(FR) La présente invention concerne un appareil (10) pour commander la production d'eau dans un puits de forage (B). Ledit appareil comprend un corps en forme de tuyau de base (12), le tuyau de base (12) ayant un passage d'écoulement axial sous forme de trou traversant axial (14) et un passage d'écoulement latéral sous forme d'orifice radial (16). Une enveloppe (18) est disposée autour du tuyau de base (12) et forme un logement de l'appareil (10). Lors de l'utilisation, l'appareil (10) fait partie d'un tubage de complétion (CS) pour le positionnement dans le puits de forage (B), l'appareil (10) étant configuré pour diriger un fluide de production dans un conduit de production (P) pour la récupération à la surface (S), réaliser une mesure quantitative de teneur en eau à l'intérieur du fluide de production, et varier l'écoulement de fluide dans le trajet d'écoulement de fluide sur la base de la mesure quantitative de la teneur en eau à l'intérieur du fluide de production pour maintenir la production d'eau à un seuil prédéterminé, ou en dessous de ce dernier.
