Abstract

The invention relates to pump technology used in oil extraction with the aid of submersible downhole rod pumps for the simultaneous but separate lifting of formation fluid during the production of two formations in a single well. The assembly comprises a drive, and an upper and a lower downhole piston pump, each connected to its own rod string. The assembly is also equipped with a housing, a yoke and a common hollow rod string, the latter being secured to the upper part of the yoke, to which the rod strings of the upper and lower downhole piston pumps are fastened from below. The rod string of the upper pump is hollow and communicates with the hollow piston of said piston pump and with a conduit provided in the yoke, as well as with the common hollow rod string. The rod string of the lower downhole piston pump is mounted between the cylinder of the upper downhole piston pump and the pump assembly housing. The upper downhole piston pump is offset from the longitudinal axis of the pump assembly housing. While using a single standard drive and two piston pumps, the operating reliability of the submersible piston pump is increased and the time between overhaul is extended.
