FIELD: oil production industry.
SUBSTANCE: proposed plant is designed for completion of oil and gas wells producing hydrocarbon materials. Plant contains deep well pump with delivery and suction valves and pump drive made in form of stepped cylinder with piston. Pressure accumulator is made in form of elastic ball placed in larger step of cylinder. Pump plunger is sealed in upper part by gland packing. Interaction of pump piston with drive is provided by water hammer. Oil is used as intermediate liquid in drive.
EFFECT: provision of effective recovery of oil or gas at minimum expenses.
