ABSTRACT:
A pump (10) is provided for pumping a fluid (14) from a borehole (12). The pump includes first and second pumping strings (20, 22) extending into the borehole and a return string (50) extending out of the borehole and to a storage tank (18). An upstroke cylinder (34) is slidably mounted for reciprocation on the first pumping string (20) and a downstroke cylinder (38) is slidably mounted for reciprocation on the second pumping string (22). A pump barrel (80) is slidably mounted to the return string (50) and forms a pumping chamber (86). Fluid from the borehole enters the pump chamber (86) through a one-way check valve (84) to equalize the fluid pressures between the pumping chamber and borehole. A pumping fluid is then entered into the first pumping string (20) to urge the upstroke cylinder (34) to the extended position, tensioning a cable (108) to move the pump barrel (80) and downstroke cylinder (38) to the retracted positions pumping the fluid in the pumping chamber up the return string (50). The pumping fluid at the predetermined pressure is then entered into the second pumping string (22) to move the downstroke cylinder (38) to the extended position, moving the upstroke cylinder (34) to the retracted position. Interconnecting lugs (42, 88) on the downstroke cylinder and pump barrel cause the pump barrel to move to the extended position with the downstroke cylinder.
