FIELD: oil and gas industry.SUBSTANCE: invention relates to oil-field equipment, particularly to downhole landing for dual production and injection. Landing includes two string of coaxially mounted tubing strings of different diameter, pump, device for separation of flows of pumped and extracted liquid, valve in the line of pumped liquid, packer for separation of the producing and injection of benches and wellhead equipment. As a pump used electric centrifugal pump. Device for separation of flows of pumped liquid is extracted above the pump. Between the pump and packer is installed moving unit in which is mounted load-carrying tube for passage of pumped fluid, connected in the upper part with fastener arranged at the device level for separation of flows of pumped and extracted liquid. Valve on the line of pumped fluid pumping is located below the packer, which is a part of the packer arrangement including disconnectors of columns, flushing and tubing anchor.EFFECT: increasing of reliability and safety of operation, simplified mounting and possibility of oil production in a larger volume.3 cl, 1 dwg |
