FIELD: process engineering.SUBSTANCE: invention relates to oil production and may be used in green oil field treatment. Proposed method comprises three-stage separation of well water-and-gas-saturated fluid, and compressing separated gas at compressor station. In compliance with this invention, degassed and dehydrated oil with residual gas saturation (de-ethanised oil) is fed into, instead of final separation stage separators, buffer tank (overpressure tank) to retain valuable hydrocarbons Cand Cin commercial oil to be fed into condensate pipeline.EFFECT: higher yield of hydrocarbons, lower material and power costs.1 dwg |
