CLOSED SYSTEM FOR COLLECTING AND TREATING OIL AND GAS IN OIL FIELD

摘要

FIELD: oil and gas production. SUBSTANCE: closed system contains wells connected to group measurement installations, separators of the first and end oil separation steps, and oil treatment plant. System is provided with absorber with its entry connected to pipeline for withdrawal of gas from the first-step separator, and exit of saturated oil from absorber is connected with pipeline for withdrawal of oil from the same separator. Product of oil well in the form of oil-gas-water mixture comes to the first separation step. Gas stream from the separator is directed into absorber, into which stable oil is simultaneously introduced as sprinkling means from stabilization unit of absorber. Gas-saturated mixture is mixed with oil from separator and fed into the end separation step and therefrom to treatment plant. EFFECT: enhanced efficiency of treatment. 1 dwg
