Abstract: front page image
(EN)The present invention relates to an artificial lift system using a downhole reciprocating pump with a double action piston for oil wells. The pump comprises a plunger (4) moved by the mechanical or hydraulic actuation rod (3), and is characterised by double action pumping, that is to say during both strokes of the reciprocating movement. The suction valves (2) move in opposite directions in each stroke, as well as the discharge valves (1), allowing the pumped fluid to flow through the inner tube (5) during the ascending stroke and through the annular space between the outer tube (6) and the inner tube (5) during the descending stroke. This downhole double action pump can be used both in the conventional, mechanical pumping system, known as pumpjack, using the rods and all the existing actuation systems, and in the actuation systems using a hydraulic cylinder (13), as supported by this patent.
(FR)La présente invention concerne un système d'élévation artificielle utilisant une pompe alternative à piston à double action dans le fond de puits de pétrole. Ladite pompe comprend un piston (4) déplacé par la tige (3) d'actionnement mécanique ou hydraulique, et se caractérise par un double pompage, c'est-à-dire dans les deux courses du mouvement alternatif. Les valves d'aspiration (2) se déplacent dans des sens opposés à chaque course, de même que les soupapes de refoulement (1), permettant le passage du liquide de pompage à l'intérieur du tube interne (5) lors de la course ascendante et par l'espace annulaire entre le tube externe (6) et le tube interne (5) lors de la course descendante. Cette pompe de fond de puits à double action peut être utilisée dans un système de pompage mécanique classique, connu sous le nom de « chevalet de pompage », utilisant les tiges et tous les systèmes d'actionnement existants, ou dans les systèmes d'actionnement par cylindre hydraulique (13), comme décrit dans ce brevet.
(PT)A presente invenção refere-se a um sistema de elevação artificial utilizando bomba alternativa de pistão de dupla ação em fundo poços de petróleo. Referida bomba compreendendo um êmbolo (4) movimentado pela haste (3) do acionamento mecânico ou hidráulico, caracterizada pelo bombeamento duplo, isto é, em ambos os cursos do movimento alternado. As válvulas de sucção (2) se movimentam em sentidos opostos a cada curso bem como as válvulas de descarga (1), possibilitando a passagem do fluido do bombeado por dentro do tubo interno (5) no curso ascendente e pelo espaço anular entre o tubo externo (6) e tubo interno (5) no curso descendente. Esta bomba de fundo de poço de dupla ação pode ser utilizada tanto no sistema de bombeio mecânico convencional, conhecido como "Cavalo de Pau", utilizando as hastes e todos os Sistemas de Acionamentos existentes, ou nos sistemas de acionamento por cilindro hidráulico (13) suportado por esta patente.
