FIELD: oil producing industry.
SUBSTANCE: proposed device is designed for use at simultaneous separate production of oil from two beds by means of deep-well sucker-rod pump units. It contains plunger with cylinder, suction and delivery valves, side valve to take off liquid from upper bed, packer separating said beds and arranged lower than pump intake. Plunger of pump is provided with smaller diameter plunger arranged lower and furnished with delivery valve. Side valve is located in lower end face part of larger size cylinder. Additional delivery valve arranged in upper part of smaller diameter plunger communicates with space formed by outer surface of smaller diameter plunger and larger diameter cylinder of pump.
EFFECT: provision of operation of plant irrespective of location of bed with larger formation pressure.
