FIELD: oil industry.
SUBSTANCE: invention relates to oil industry. Method of creating a combustion source in an oil reservoir includes heating bottomhole formation zone around injection well, feeding into bottomhole formation zone combustible material and oxidising agent. Heating of bottomhole formation zone around injection well is performed to temperature sufficient for ignition of combustible material in formation in contact with oxidising agent, and is performed by heating combustible material before feeding into bottomhole zone without air access. Combustible material is vegetable oil, hydrocarbons or mixture thereof.
EFFECT: technical result is high efficiency and safety of in-situ combustion by means of creation in bottomhole formation zone of injection well combustion source while maintaining injection capacity of bottom-hole zone, possibility of initiation of in-situ combustion in deep deposits with high power of oil-filled formation.
