Abstract
L'invention concerne une unité de pompage de double puits (12) comprenant deux unités de vérins hydrauliques (26), une pour chaque puits (chaque unité de vérins (26) comprenant de préférence trois vérins hydrauliques). Chaque unité de vérins hydrauliques est raccordée à une première pompe à piston (18) et à une seconde pompe à piston (20). L'arbre d'entraînement (40) de la première pompe à piston (18) est accouplé à l'arbre d'entraînement (38) de la seconde pompe à piston (20) et à un rotor d'un moteur d'entraînement (16). La pompe à piston (18) et la pompe à piston (20) sont de préférence des pompes à piston à déplacement variable qui sont commandées par un dispositif de commande basé sur un microprocesseur (44) de sorte que pendant la course descendante du vérin hydraulique (26), la pompe à piston (18) fonctionne comme un moteur hydraulique entraînant la pompe à piston (20) et pendant la course ascendante du vérin hydraulique (26), la pompe à piston (20) fonctionne comme un moteur hydraulique pour fournir une assistance à la pompe à piston (18).
