Abstract
FIELD: oil-producing industry. SUBSTANCE: method for treatment of bottom-hole formation zone includes injection into formation of suspension consisting of ferric chloride with sizes of particles smaller than sizes of pore channels in the amount of 0.1-2 kg per meter of perforation interval and fractions of light hydrocarbons C-Cin the amount of 0.1-2 cu.m per meter of perforation interval. Later, oxidation is conducted by injection of emulsion consisting of fractions of light hydrocarbons C-Cin the amount of 0.1-5 cu. m per meter of perforation interval and aqueous solution of hydrogen peroxide in the amount of 0.8-40 cu.m per meter of perforation interval with 2-60% concentration. Then, reagents are forced are into formation by spacer fluid. Injection of suspension ensures saturation of bottom hole with light hydrocarbons and transportation of particles of ferric chloride directly to formation pore channel. Use of hydrogen peroxide makes it possible to perform treatment of well with horizons of high formation pressure. EFFECT: higher efficiency of treatment due to increased degree of sweep of formation and provision of method application under conditions of high formation pressure.
