ABSTRACT:
An improved seal assembly for sealing the annulus between a free-type downhole hydraulically actuated pump and the pump cavity within which the pump is telescopingly received downhole in a borehole. A connector body is affixed to the upper end of the pump, and a packer nose assembly is affixed to the upper end of the connector body. The connector body has a circumferentially extending groove formed thereabout, and a flow passageway wherein the connector body interconnects the interior of the hollow connector body to the inner wall surface of the groove. A resilient seal is received within the groove. The seal is quadrangular in cross-section. When the pump is seated downhole in the collar of the cavity, power fluid flows through the packer nose assembly, through the connector body, and to the hydraulic pump; while at the same time, power fluid flows into a working chamber formed between the innermost surface of the resilient seal and the bottom of the groove, thereby expanding the resilient seal outwardly into sealed engagement with the interior surface of the collar. This action precludes flow of power fluid between the pump housing and the collar, and at the same time, stabilizes the pump so that it is firmly held into operative position until the flow of power fluid is discontinued.
