FIELD: oil production industry, particularly methods for regulating oil-field development and increasing oil recovery from non-uniform permeable formations.
SUBSTANCE: method involves alternately pumping banks of isolating compound in production and/or injection wells, wherein alcoholic fraction obtained from caprolactam production with 5-20% mass concentration is used as solvent.
EFFECT: increased oil recovery due to isolation of high-permeable water-bearing formation areas in production well, increased formation coverage, increased oil displacement from low-permeable oil-saturated areas due to increased oil recovery factor and change in wetting ability of rock surface.
