Modular top loading downhole pump

摘要

A method and apparatus for improving the production efficiency of a well and preventing gas lock. The apparatus is a downhole pump and comprises a barrel, a reciprocating plunger and a body having a plurality of inlet valves. The apparatus does not require outlet valves. The body and inlet valves are positioned above the barrel and plunger, thus eliminating gas lock. Fluids enter the body through the valves and, during upstrokes of the plunger, are forced up the tubing string to the surface equipment. Modularity of the components permits pump components to be changed as the productivity of the well fluctuates and also allows production of more fluids with a smaller casing.

主权项

1. A downhole pump positioned below the tubing string of a well for pumping fluids, the pump comprising:
a body; at least one valve connectable with the body, wherein the at least one valve comprises a first aperture through which fluids enter the at least one valve and a second aperture through which fluids exit the at least one valve and enter the body; and a plunger moveable between an upper first position and a lower second position, wherein the upper first position is below the at least one valve; wherein during plunger downstrokes, fluids entering through the first aperture enter the body and wherein during plunger upstrokes, fluids move up the tubing string.
