FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and gas industry, in particular to methods for extracting various types of oils (from especially light to bituminous) at fields at any stage of development using all types of heat carriers and chemicals. The method includes opening the reservoir with at least one well, hydraulic fracturing, cyclic injection of the energy carrier into the well, stopping the well for reaction and oil production. In each cycle, the entire volume of the energy carrier is pumped in parts, the value of which is determined by the achievement of the minimum hydraulic fracturing pressure with subsequent well stops between them for the time of pressure drop to the initial reservoir in an amount that provides the total volume of the energy carrier.
EFFECT: oil production increases due to the uniform radial distribution of the energy carrier in the oil-saturated zone of the reservoir.
