EQUIPMENT FOR GAS-LIFT METHOD OF OIL PRODUCTION Russian patent published in 2001 - IPC

FIELD: production of liquid of gas-liquid fluid media from producing wells, particularly, equipment for gas-lift method of oil production from group of development wells. SUBSTANCE: equipment includes source of working agent, for instance, gas or gas- liquid mixture, pipelines for supply of working agent and respective channels of development wells, group measurement plant provided with gas-liquid separator and connected with pipeline of discharge of recovered hydrocarbon product from wells and oil gathering main. Equipment includes low- and high-pressure gas separators interconnected via unit of booster pumps. In this case, gas side of each booster pump is communicated via manifold with gas sides of low-pressure separator, and/or separator of measurement unit, and/or independent source of low-pressure gas, or with starting line of gas- lift wells; and liquid side is communicated with liquid sides of low- and high-pressure separators, and/or separator of group measurement plant communicated in its turn with oil gathering main. High- pressure separator is communicated with gas side of unit of booster pumps and with manifold for gas supply to development wells; and low-pressure separator and/or separator of measurement plant is communicated with oil gathering main. In addition, equipment includes reagent facilities unit connected with liquid side of booster pumps unit and pipelines for supply of working agent to wells. EFFECT: simplified equipment due to exclusion of high-pressure gas line between gas source and operating wells. 2 cl, 2 dwg
