OIL PRODUCTION SYSTEM Russian patent published in 1998 - IPC

FIELD: oil and gas production industry. SUBSTANCE: this relates to mechanized recovery of gas-oil mixture from wells. System has two or more wells with casing clearance 2, pump-compressor pipes 3, down-hole pumps 4 with drive 5, compressor 6 with suction pipe union 7, common manifold 8 which connects suction pipe union 7 with casing clearance 2 of wells, pressure regulators 9, 10, discharge gas pipeline 11, gas pipeline 12, non-return valve 13, oil pipeline 14, group measuring unit 15. At pressure reduction in casing clearance below preset value, come into operation are respective pressure regulators. In result, gas from casing clearance comes to common manifold and this causes pressure rise at compressor inlet up to initial value. EFFECT: high efficiency. 1 tbl, 1 dwg
