FIELD: oil and gas industry.
SUBSTANCE: oil production method includes delivery of a working fluid to an injection well and extraction of oil products through a production well with further separation of associated gas from oil and its burning. Burning of associated gas is carried out with plenty of outdoor air. Products of associated gas combustion are cooled; water and liquid carbon dioxide gas are separated and remaining gaseous phase is released. In order to obtain a working fluid liquid carbon dioxide gas is mixed up with water steam generated during heating of prepared water by products of associated gas combustion.
EFFECT: production effectiveness, ecological and economical efficiency of oil deposits development due to use of products of associated gas combustion.
