description FIELD: oil extractive industry. ^ SUBSTANCE: method includes pumping of working agent through force wells in non-stationary mode, determining character of oil-saturated depths distribution, operation of wells located in areas of higher values of flowing oil-saturated depths under conditions of forced extraction of liquid, periodically through force well gas-water mixture is fed, which consists of bed water and clean oil gas dispersed in it with size of bubbles up to 5 micrometers, while during all pumping pressure in face of force wells is kept no more than 0.7 of mountain pressure. ^ EFFECT: higher oil yield due to increase of effect of influencing process and due to increase of displacement coefficient. ^ 1 ex, 1 tbl
