FIELD: oil and gas industry.
SUBSTANCE: method of oil influx intensification in wells with complex profile involves injection to the well of carbon- or hydrocarbon-containing and oxygen-containing substances not higher than the limits of the interval intended to be treated. Well water-intake capacity is determined before the treatment interval is cutout; then, flushing fluid on hydrocarbon basis is pumped. After that, solution of mixture of oxygen-containing chemicals mixed with thickener is supplied in the volume which is not less than one third of column volume at treatment interval, and the above composition is pumped with flushing fluid on hydrocarbon basis. Well heater is delivered to treatment interval and switched on; and thermal gas chemical reaction is initiated, the completion of which is recorded as per stabilisation of pressure values on pressure gauges installed on heads of tubing strings in annular space, and efficiency is determined as per the increase in well water-intake capacity.
EFFECT: increasing oil influx intensity in wells with complex profile.
