FIELD: oil industry.
SUBSTANCE: invention relates to oil industry and is intended for treatment of bottomhole zone of injection and production oil wells. Method of treatment of bottomhole zone of oil formation includes treatment of formation with gas-liquid solution obtained in formation by means of sequential pumping into formation first of gas-releasing water solution, and then of acid water solution. After injection of acidic aqueous solution, solvent is injected, which is selected according to preliminary laboratory experiments from condition of most effective dissolution of asphalt-resinous deposits of formation from benzene, toluene, xylene or their mixture.
EFFECT: increased efficiency of oil formation treatment for further extraction of oil products.
