FIELD: oil and gas industry.
SUBSTANCE: oil production method by oil formation stimulation, comprising selecting oil from the production well, separation of the water and associated gas therefrom in separator, gas combustion in heat engine, use of the resulting in energy engine for driving pumps and electric generator, water heating and pumping it into the formation, combustion products injecting into the formation, characterized in that the gas supplied to the heat engine is taken from the annulus of the production well. A well operation mode is selected providing the maximum value gas selection due to the optimum dynamic level in the well, the gas from the separator is pumped into the formation, and water is heated to the temperature exceeding the wax melting point for a given field.
EFFECT: increased efficiency of oil production while reducing negative environmental impacts.
