Abstract:

A downhole pump is reciprocated subsurface for the purpose of lifting fluid from an underground borehole to the surface or other suitable storage location. As the fluid being pumped may contain gas, the efficiency of the pump may decrease to the point where no fluid is pumped due to the compression and expansion of gas within the downhole pump. This condition is commonly described as gas lock, and, when encountered, can prevent the pump from displacing any fluid, resulting in no efficiency and no work performed. Installed as an integral part of the downhole pump assembly, the device described herein effectively, mechanically, and positively prevents the gas locked condition, and, additionally, efficiently handles suspended solids due to its design incorporating no moving parts nor small fluid passages.
