DEVICE FOR OPERATION OF GAS WELLS Russian patent published in 1997 - IPC

Abstract RU 2087681 C1

FIELD: oil and gas production industry. SUBSTANCE: this is used in producing oil with high gas factor. Device has string of tubes and located over its length at points of couplings are partitions with holes which accommodate pipe unions of low-adhesive material located successively coaxially and with clearance relative to each other. In process of well operation, pipe unions in cooperation with tubes of string create gas filled heat-insulation annular spaces which reduce coefficient of heat transfer from gas-oil mixture to rocks. Reduced heat-transfer and pipe unions made of low-adhesive material prevent formation of hydroparaffin deposits in well. EFFECT: high efficiency. 2 cl, 1 dwg
