FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises drilling with the boundaries of one formation of parallel horizontal or inclined horizontal injection wells and production well, injection of heat carrier in injection wells and oil withdrawal from production well. Production well is located at equal distance from injection well bottoms which rules out heat carrier outburst bur allows hydrodynamic communication with injection wells. Injection wells are provided with two parallel channels with filters alternating over production reservoir length. Channels are used for injection of heat carrier while, after reservoir heating, one of said reservoirs is used for in-well product flow towards production well.
EFFECT: higher efficiency.
