Patent
CA 2619570
A single conduit lift pump is disclosed that only requires a single fluid conduit for both the driving fluid and the pumping action of the pump in a well bore. Fluid pressure communicated to the pump by the single fluid conduit drives the pump to load a resilient member. The fluid pressure is cycled off to allowing the lift of fluid by action of the resilient member upon the single fluid conduit. The single fluid conduit makes this pump suitable for downhole operations for the oil and gas production industries in wells that have substantial water cut that inhibits the production of gas.
Pompe élévatoire à conduit unique nécessitant un seul conduit hydraulique pour le fluide pousseur et l'action de pompage de la pompe dans un trou de forage. La pression hydraulique transmise à la pompe par ce conduit unique fait que la pompe charge un élément souple. On prévoit un cycle d'interruption de pression hydraulique pour permettre l'élévation de fluide par l'action de l'élément souple sur le conduit en question, lequel rend la pompe décrite appropriée aux opérations de forage dans la production de gaz et de pétrole, pour les puits ayant une teneur en eau substantielle qui empêche la production de gaz.
