FIELD: oil and gas production.
SUBSTANCE: invention relates to stabilisation of gas-saturated oil. Proposed method comprises two-stage separation at 20-80°C with separation of gas at 1st separation stage at 0.11-0.16 MPa. It comprises also separation of degassed oil at 2nd separation stage at 0.01-0.06 MPa to obtain separated oil and gas. Separated gas is sucked off by degassing device, for example, ejector operated on associated gas from oil field separation stage. Here, extracted gas is mixed with 1st separation stage gas. Produced gas mix is cut in stable condensate and dry gas. Then, stable condensate is mixed with separated oil to feed stabilised oil and dry gas to consuming equipment.
EFFECT: higher yield of separator oil.
