Summary:FIELD: oil industry, particularly enhanced recovery methods for obtaining hydrocarbons. ^ SUBSTANCE: method involves drilling horizontal injection and producing wells in oil field; injecting fine water-gas mixture in water-oil contact zone via injection wells, wherein water-gas mixture density is less than that of water under reservoir conditions, mixture temperature is higher than initial reservoir temperature and less than water boiling temperature under injection well head pressure; simultaneously extracting product from oil rim and water-saturated reservoir. Fine water-gas mixture may be additionally injected in oil rim zone. ^ EFFECT: increased efficiency of oil displacement due to increased reservoir area coverage. ^ 2 ex
