Title (EN) DOWNHOLE HYDROCARBON PUMP
(FR) POMPE A HYDROCARBURES POUR FOND DE PUITS
Abstract:
(EN) An improved downhole valve pump for producing hydrocarbon fluids from a reservoir. A reciprocating valve element (22) attached to a stem (24) selectively contacts a valve seat (18) to prevent fluid flow through a valve housing (10). Reciprocation of the valve element (22) and stem (24) is guided with first and second guides (34, 36) which restrict lateral movement of the valve within the housing (10). A gasket (40) can be positioned to facilitate makeup and to attenuate forces exerted by the moving valve element (22). The invention increases hydrocarbon fluid flow through the housing (10) by eliminating components restrictive to such flow, thereby increasing the overall pump efficiency.
(FR) Pompe améliorée à soupape pour fond de puits qui permet de produire des fluides hydrocarbures à partir d'une roche magasin. Un élément soupape (22) à mouvement de va-et-vient, attaché à une tige (24), vient en contact de manière sélective avec un siège (18) de soupape pour empêcher l'écoulement de fluide par un carter (10) de soupape. Le mouvement de va-et-vient de l'élément soupape (22) et de la tige (24) est guidé par des premier et second dispositifs de guidage (34, 36) qui restreignent le mouvement latéral de la soupape à l'intérieur du carter (10). Un joint d'étanchéité (40) peut être placé de manière à faciliter le vissage et à atténuer les forces exercées par l'élément soupape (22) mobile. La présente invention permet d'augmenter l'écoulement de fluide hydrocarbure par le carter (10) en éliminant les composants qui restreignent cet écoulement, ce qui améliore l'efficacité totale de la pompe.
