Patent CA-2696600-A1 (CA)
Inventor: PUGH TOBY
IPC: E21B43/12
Filed: 2010-03-09
Abstract: A hydraulic pump avoids problems with gas lock found in conventional pumps. The pump draws in production fluid in a lower pump volume during the pump's upstroke and diverts the produced fluid to an upper pump volume during the downstroke. Spent power fluid is communicated to the upper pump volume during the pump's upstroke. The pump piston in the upstroke expels the entire volume via a check valve that communicates the upper pump volume with a discharge outlet. The check valve increasing the discharge pressure of the upper pump volume, the upper pump volume of the spent power fluid being greater than the upper pump volume, and the upper pump piston compressing produced gas in the upper pump volume all combine to prevent or reduce the chances that the pump will gas lock during operation.
