FIELD: oil and gas industry.
SUBSTANCE: method comprises pumping into the annular space of the well of emulsifier at a rate of 60-80 g per 1 m3 of extracted water, discharge of gas from annular space into the air. After formation in annular space of finely dispersed water-oil emulsion it is flushed into the tubing string by heat carrier until full removal of asphaltene-resin-paraffin deposits.
EFFECT: well cleaning efficiency improvement.
