    摘要: Pump assemblies for subsurface fluid reservoirs include an upper portion connected to a fluid conduit extending to the surface, a lower portion connected to the upper portion and in fluid communication with a fluid reservoir of the wellbore, and a plunger assembly movably located within the upper and lower portion of the pump assembly. As the fluid pressure within the production tubing string, fluidly isolated from the inner tubing string, increases, fluid is forced into the pump assembly moving the plunger assembly upward to draw fluid into the lower portion of the pump and forces fluid out of the upper portion of the pump assembly and into the inner tubing string. As the fluid pressure within the production tubing string decreases, movement of the plunger assembly descends displacing fluid from the lower portion of the pump assembly into the upper portion through a fluid passageway extending through the plunger assembly.

    摘要: Pump assemblies for use with a subsurface fluid reservoir include an upper barrel connected to a fluid filled conduit extending to the surface, a lower barrel connected to the upper barrel and in fluid communication with the reservoir, and a plunger assembly movably located within the upper and lower barrels. As the fluid pressure within production tubing, external to the pump assembly, increases, movement of the plunger draws fluid into the pump. As the fluid pressure within the production tubing decreases, the plunger pushes fluid into the production tubing.
