Title (EN) HYDRAULICALLY ACTUATED DOUBLE-ACTING POSITIVE DISPLACEMENT PUMP SYSTEM FOR PRODUCING FLUIDS FROM A DEVIATED WELLBORE
(FR) SYSTÈME DE POMPE À DÉPLACEMENT POSITIF À DOUBLE ACTION ACTIONNÉ HYDRAULIQUEMENT POUR LA PRODUCTION DE FLUIDES À PARTIR D'UN PUITS DE FORAGE DÉVIÉ
Abstract:
(EN) A submersible, hydraulically actuated, multi-stage double-acting positive displacement pump system is provided. The system has a hydraulically actuated reciprocating linear double-acting motor centrally disposed between and connected to double-action fluid pumps on either side of the motor, with pistons of each of pump and the motor all in the annular space between an inner wall of the apparatus' cylindrical body and the outer wall of a cylindrical production fluid conduit concentrically disposed within the body, to pump wellbore fluid from outside the assembly through the pumps and into the central production fluid conduit. The rate and direction of hydraulic fluid flow through the actuator may be controlled by VFD motors and PLC controller on the ground, and through at least one electromechanical valve and two limit switches mounted to the downhole components.
(FR) L'invention concerne un système de pompe à déplacement positif à double action, à étages multiples, à actionnement hydraulique et submersible. Le système comprend un moteur à double action linéaire alternatif à actionnement hydraulique disposé de manière centrale entre et relié à des pompes à fluide à double action de chaque côté du moteur, avec des pistons de chaque pompe et du moteur tous dans l'espace annulaire entre une paroi interne du corps cylindrique d'appareil et la paroi externe d'un conduit de fluide de production cylindrique disposé de façon concentrique à l'intérieur du corps, pour pomper le fluide de puits de forage depuis l'extérieur de l'ensemble à travers les pompes et dans le conduit de fluide de production central. La vitesse et la direction du flux de fluide hydraulique à travers l'actionneur peuvent être commandées par des moteurs VFD et un dispositif de commande PLC sur le sol et par l'intermédiaire d'au moins une soupape électromécanique et de deux commutateurs limites montés sur les composants de fond de trou.
