FIELD: oil and gas industry.
SUBSTANCE: method for heating producing oil-bearing formation includes delivery of water pre-heated by the heater placed at the surface under pressure through injecting well. The device for heating producing oil-bearing formation comprises a pump with drive, which input is connected to water tank and through the heater to the injecting well. At that a nuclear reactor is used as the source of thermal energy. In the bottomhole there is a heat exchanger, to which circulation loop with heat carrier of the nuclear reactor is connected through two flexible coil tubings. Upon heating at the surface water is heated additionally within the whole length of the well and in the bottomhole.
EFFECT: improved efficiency of the process.
