FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil industry, in particular to the compositions used to isolate the inflow of water into production oil wells and intensify oil production. Composition comprises 5–30 % by weight of oleic acid, 1–5 % by weight of a mixture of organic sulphonic acids with 10–18 carbon atoms, 20–30 % by weight of an aliphatic alcohol, 3–10 % by weight of ethanolamine, and fresh water with the remainder.
EFFECT: technical result is an increase in the efficiency of conducting waterproofing works and intensification of oil production due to the use of a homogeneous composition of selective action to the water-saturated areas of terrigenous and carbonate reservoirs.
