FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil industry, and in particular to compositions for the destruction of oil-water intermediate emulsion layers stabilized by mechanical impurities. Invention relates to a composition for the destruction of the intermediate layers in the apparatus for treatment of oil on the basis of organic sulfur compounds and monoethanolamine, including an additional aliphatic alcohol, and as organic sulfur compounds, a mixture of olefin sulfonic acids C10-C18 in the form of a 45 % aqueous solution in the following ratio of components, vol. %: monoethanolamine – 15, 45 % aqueous solution of a mixture of olefin sulfonic acids – 55, aliphatic alcohol – 30.
EFFECT: effective destruction of oil-water intermediate emulsion layers.
