FIELD: oil producing industry.
SUBSTANCE: invention is designed for in group hydraulic drives of sucker-rod pumps in cluster wells. Proposed drive contains two power hydraulic single-acting cylinders for each pair of cluster wells, and hydraulic distributor. Plunger of hydraulic distributor is installed in housing with clearance to provide longitudinal displacement, and it forms chambers connected by supply channels with spaces of hydraulic cylinders and with oil pump. Pump sucker rods are connected with rods of hydraulic cylinders by chains laid over system of sprockets. One end of plunger is mechanically coupled with piston of one of hydraulic cylinders through compression springs, carriage and additional rod. Drive is furnished with metering oil pump.
EFFECT: improved operation reliability of drive, and its efficiency and simplified design.
