FIELD: oil-and-gas industry.
SUBSTANCE: proposed method consists in revealing the oil reservoir by field and geophysical researches, estimating its hydrodynamic activity by repeated geophysical measurements and defining variation of measured parameters in time, and drilling holes directly into said oil strata. In compliance with this invention, revealed strata is localised by drilling horizontal hole across direction of said strata. Thickness of oil strata is defined to drill second horizontal hole in direction of said strata over its axial line. At a time, current thickness of said strata and drilled hole position are defined. Note here that said hole is drilled along the crest. Then, isolating agent is injected in said hole to make an artificial cap. Thereafter, under said cap, at depth larger than isolating agent penetration depth, drilled is at least one horizontal hole to extract oil.
EFFECT: oil extraction directly from oil strata.
