FIELD: oil extractive industry, in particular, engineering of systems for forcing liquid into reservoir in case of water-flooding. ^ SUBSTANCE: plant includes well with water or oil reservoirs, packer, tubing string and vessel, all connected to a pump through connecting pipeline, while the tubing string and vessel are partially filled with technological liquid, while tubing string is provided with forcing and suction valves, positioned, respectively, below and above the packer. In accordance to invention, tubing string is provided with substance separator, positioned at substance separation boundary "bed water - technological liquid" with possible movement together with it and being in contact with internal surface of tubing string. Internal surface of tubing string is lined, at least in zone of movement of substance separator. As lining cover, materials are used having hydrophilic surface. ^ EFFECT: increased efficiency of plant (pump or vessel), increased service life of same. ^ 1 dwg |
