FIELD: oil production industry. SUBSTANCE: according to method, pressure-forced into bottom-hole zone of well is water-in-oil emulsion. Metallic magnesium is introduced into perforation interval. Solution of muriatic acid is pumped-through and pressure-pushed into oil bed at gradual reduction of pushing-through pressure. After that, well is washed-through with hot oil. Application of aforesaid method ensures levelling of permeability in low-permeable and high-permeable zones. EFFECT: higher efficiency.
