FIELD: oil and gas producing industries.
SUBSTANCE: device is designed for separate production of oil and gas with out lifting of formation water to surface. Device contains fixed cylinder with oil and water intakes, movable plunger including suction and delivery valves and two pistons. Pistons are connected by branch pipe with oil intake ports. Cylinder is made stepped. Upper step of cylinder is of diameter exceeding that of lower step. Each step is hydraulically coupled with well annulus. Free piston is installed additionally in lower step of cylinder.
EFFECT: increased efficiency in oil production, reduced losses of light hydrocarbons, power consumption and capital outlays in process of development of oil deposit.
