Title:
ARTIFICIAL LIFT AND TRANSFER PUMP
Document Type and Number:
WIPO Patent Application WO/2010/118535
Kind Code:
A4
Abstract:
A downhole pump for use in oil and gas wells and a method for using same is provided. The pump includes a cylindrical housing having a pair of opposing pistons disposed therein, connected together by a connecting rod that reciprocates within the housing. Each piston separates an outer compression chamber from an inner chamber within the housing, the compression chambers configured to draw in and expel target fluids through separate inlet and outlet check valves. Power fluid, such as pressurized gas or fluid, is used to reciprocate the piston assembly within the housing thereby causing target fluids to be pumped through the compression chambers. A reversing sleeve is disposed about the connecting rod between the pistons, thereby separating the inner chambers, to control the flow of power fluid to the piston assembly through ports disposed in the housing sidewall thereby enabling movement of the piston assembly in the housing.
