FIELD: heating.SUBSTANCE: group of inventions relates to methods and devices for heating of hydrocarbons in underground reservoir. The method of heating of underground zone includes the creation of cavity for placement of the underground heating device. The named underground heating device comprises the following: the combustion gas line housing enclosing the combustion gas line; at least two combustion chambers; at least one line for fuel supply; at least one line for oxygen supply and exhaust line for exhaust of combustion gas. At least two combustion chambers are located in the combustion gas line housing. The fuel supply line is intended for combustible fuel supply at least in one combustion chamber. The oxygen supply line is intended for oxygen supply at least into one combustion chamber. The distance between combustion chambers is at least 304.8 m (1000 ft) and calorific capacity is at least 3.6·10kJ per hour (3.41·10BTE per hour). The underground heating device is installed in the cavity. Then the underground heating device is operated.EFFECT: technical result is improvement of efficiency of hydrocarbon production.10 cl, 1 dwg |
