Submergible pump installation |
摘要 |
A submergible pump installation for wells comprising a submergible pump assembly adapted to be landed in position within the well bore for pumping well fluids to the surface, together with a safety system for the well including a subsurface valve or valves for maintaining the well under control as the pump is run into and removed from the well. At least one subsurface valve of the system is hydraulically actuated by the discharge pressure of the pump with the pressure fluid being conducted to the valve by a conducting means located exteriorly of the pump housing. The invention also contemplates the use of a novel poppet-type subsurface valve which may be suitably pressure balanced so that it is capable of being actuated by relatively low hydraulic control pressure supplied by the pump.
