ABSTRACT:
A submersible pump and safety system for installation in wells having a submersible pump adapted to land within a well flow conductor for pumping well fluids to the surface plus a subsurface safety valve or valves for maintaining the well under control as the pump is run into and removed from the well. The subsurface safety valve is hydraulically actuated by the discharge pressure of the pump. The landing nipple in which the pump and safety valve are mounted has longitudinal flow passageways to communicate pump discharge pressure to the safety valve. The landing nipple and longitudinal flow passageways are designed for improved reliability and minimize the possibility of mechanical damage interrupting control fluid flow to the safety valve.
