1. Способ вытеснения остаточной нефти из обводненного нефтяного пласта, разбуренного как минимум одной нагнетательной и одной добывающей скважинами, включающий активацию микрофлоры закачкой в аэробную зону нагнетательной скважины нефти и аэрированного водного раствора питательных веществ, отличающийся тем, что нефть, извлеченную из добывающей скважины, закачивают в нагнетательную скважину в объеме 20-30% от порового объема аэробной зоны нагнетательной скважины, при содержании в аэробной зоне нагнетательной скважины углеводородокисляющих бактерий менее 103 кл/мл или полном их отсутствии в аэробную зону вводят культуру углеводородокисляющих бактерий.1. A method of displacing residual oil from a watered oil formation drilled by at least one injection and one producing well, comprising activating microflora by pumping oil and an aerated aqueous solution of nutrients into the aerobic zone of the oil, characterized in that the oil extracted from the producing well is pumped to the injection well in the amount of 20-30% of the pore volume of the aerobic zone of the injection well, when the content in the aerobic zone of the injection well is hydrocarbon bacteria with less than 10 3 cells / ml or their complete absence, a culture of hydrocarbon-oxidizing bacteria is introduced into the aerobic zone. 2. Способ по п. 1, отличающийся тем, что к нефти, содержащей внутри фракции н-парафиновых углеводородов менее 25% углеводородов с числом атомов углерода 4 - 16, добавляют легкие фракции углеводородов. 2. The method according to p. 1, characterized in that light fractions of hydrocarbons are added to the oil containing less than 25% hydrocarbons with the number of carbon atoms from 4 to 16 inside the fraction of n-paraffin hydrocarbons. 3. Способ по п. 2, отличающийся тем, что в качестве легких фракций углеводородов используют, например, дистиллат. 3. The method according to p. 2, characterized in that the light fractions of hydrocarbons are, for example, distillate.
