FIELD: oil and gas industry.
SUBSTANCE: method involves installation of oil-well tubing string with well sucker-rod pump in a well. Additionally, the string features a liner with filter, heating cable along external surface from wellhead to the well sucker-rod pump, capillary well pipeline from wellhead to a depth below the well sucker-rod pump, entering inner space of the liner. Well operation involves simultaneous product extraction through oil-well tubing string by the well sucker-rod pump. Electric current runs over the heating cable. Mix of Intat asphaltene, resin and paraffin sediment solvent and Rekod demulsifier is injected via capillary well pipeline. Demulsifier to solvent ratio is (1:18)-(1:22). Cable with maximum heating temperature up to 105°C and maximum power up to 60 kWh is used as the heating cable.
EFFECT: enhanced efficiency of viscous oil emulsion production.
