FIELD: oil producing industry.
SUBSTANCE: invention is designed for use in oil wells with high oil-gas ratio and for wells with low flowing levels. Proposed sucker-rod pumping unit includes tubing string of which sucker-rod pump is secured consisting of cylinder, plunger with delivery valve installed in cylinder for reciprocating, and suction valve arranged in lower part of cylinder. Cylinder is provided with at least one radial hole communicating with annulus through housing secured on outer surface of cylinder and provided with at least one bypass valve. Radial hole is located higher than upper end face of plunger at its extreme lower position and lower than lower end face of plunger at its extreme upper position in cylinder.
EFFECT: increased capacity of tube sucker-rod pumps at production of oil in fields with high oil-gas ratio.
