FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil producing industry and can be employed for raising yield of producing wells of low- and medium penetrable collectors of high temperature formations of oil deposits. The composition for treatment of a bottom hole zone of collectors with low permeability contains, wt %: hydrochloric acid 6-12, hydrofluoric acid 1.5-3, organic solvent 25-30, isopropyl alcohol 25-30, silicon-organic emulsion SE-30-04 1, water - the rest.
EFFECT: upgraded efficiency of oil displacement out of formation.
