FIELD: oil producing industry.
SUBSTANCE: invention is designed for use in well sucker-rod pumping units. Proposed well sucker-rod pumping unit has sucker rod pump with plunger, cylinder, suction and delivery valves, pipe arranged concentrically relative to pump cylinder and forming with the latter a hermetic chamber with holes in upper part to let liquid pass into pump overplunger space. Side channel connects lower part of pump with annular space Linear contains additional valve in upper part. Flow divider with additional valve and through channels is arranged in upper part of liner with packer separating two strata. Through channels communicate overpacker space of well with hermetic chamber and underpacker space with pump intake in case of upper location of stratum of higher productivity, and underpacker space with hermetic chamber and overpacker space with pump intake in case of lower location of stratum of higher productivity. Level of arrangement of holes in pump housing is chosen basing on ratio of production rates of upper and lower strata.
EFFECT: provision of liquid draining from strata with different pressure by one and the same sucker-rod pump.
