FIELD: oil industry, possible use for extracting oil deposit in natural mode of extraction. ^ SUBSTANCE: in accordance to method, as extractive wells, curvilinear horizontal wells branching in horizontal plane are used. Oil is extracted cyclically by stopping and launching all extracting wells. When wells are launched, extraction of oil is continued until current bed pressure drops to 60-80% of original value, and stopping of wells is performed until current bed pressure is restored to 70-90% of original value. ^ EFFECT: increased oil yield of deposit. ^ 1 ex, 1 dwg |
