FIELD: oil producing and refining industries.
SUBSTANCE: in proposed system of complex treatment of oil well products consisting of pipelines, heat exchangers, oil heater, tank-settler and stock-oil tank, tank-settler is furnished with inner individual separating unit built in its upper zone and connected through vertical drain branch pipe with mother-distributor providing complete separation of gas and getting of stock oil and clean formation water in one tank-settler. According to proposed method of complex treatment of oil well products including separation of gas and formation water from oil, delivery o gas-water-oil emulsion into separation unit is provided tangentially to form effect of hydrocyclone and ensure uniform distribution of separated liquid through drain branch pipe in mother-distributor located under layer of water.
EFFECT: improved quality of oil treatment.
