DEVICE FOR HOT WATER INJECTION INTO WELL Russian patent published in 2010 - IPC E21B43/24 F02C7/00 

FIELD: oil-and-gas industry.

SUBSTANCE: invention related to hydrocarbons production. Device contains a production well and a device for water injection into the well, containing a pump, which inlet connected to injection well, and an electrical generator. According to the invention, after the pump by the water line, connected regenerative heat exchanger, installed in gas-turbine drive exhaust device and a heat exchanger-cooler. The gas-turbine drive contains double-shaft two-stage gas-turbine motor with internal and external shafts, a compressor, a combustion chamber, a turbine and Sterling motor, connected to the double-shaft two-stage gas-turbine motor via one of the shafts. This shaft connected with the pump, and the other one - with the electrical generator, connected electrically with the hydrocarbon pump drive. Before the Sterling motor an additional chamber installed, and the heat exchanger-cooler connected between the compressor outlet and turbine cooling system collector, by the air line.

EFFECT: complex reliability increase and formation pressure increase, improvement of hard hydrocarbons heating for their melting and evaporation.
