FIELD: oil industry, technology for cyclic forcing of liquid into oil bed during its water saturation or injection of various reagents into said bed.
SUBSTANCE: device contains packer, column of pipes with suction valve, pump. In accordance to invention mouth of device may be pressurized. Pipes column is provided with bypass channel. Pump is made in form of electric down-pump, which is mounted above suction valve in composition of pipes column below bypass channel, through which hollow of pipe column above the pump is connected to lower bed. Hollow of pipes column below the pump may be connected to upper bed during transit of liquid from behind-column space above the packer - upper bed zone into lower bed by means of a pump. Between this pump and suction valve, sensor of pressure from liquid of upper water bed is mounted in behind-column space with possible enabling and disabling of pump.
EFFECT: simplification of device with simultaneous increase of its operation efficiency.
