Abstract

FIELD: equipment for oil and gas production. SUBSTANCE: invention relates to device with housing mounted on the tube column above packer, said housing having an axial and a number of radial canals, and, placed in axial canal, a jet pump connected to cable or steel line and provided with a back valve-type mechanism enabling closing fluid flow. Reliability of device is improved by way of reducing probability of rupturing cable or steel line when lifting the jet pump due to following innovation. Housing has collar and chamber on its inner surface, and jet pump, on its outer surface, has annular groove and output unit, which is made in the form of differential piston placed concentrically in the housing and, linked to the latter, spring- loaded two-arm pivot rods. These enter the housing annular space when differential piston is in its lower position, are in the annular groove of jet pump with piston's being in intermediate position, and interact with collar when piston is in its top position. EFFECT: increased reliability.
