摘要

FIELD: obtaining oil from a multiple-zone well, particularly equipment and technology for cyclic fluid injection in oil-bearing reservoir during reservoir flooding or reagent injection.;SUBSTANCE: plant comprises packer, pipe string with injection and suction valves arranged below and over packer correspondingly, as well as pump installed on day surface of the well. Cylinder interior section located over piston is communicated with well interior through technological orifices, which prevent liquid "swabbing" during plant operation. Piston is air-tightly installed inside cylinder. Pump arranged on day surface is made as hydraulic cylinder with driving piston inside it. Working liquid is oil, which fills pipe string over cylinder and pump hydraulic cylinder interior.;EFFECT: simplified structure along with increased operational efficiency.;1 dwg
