COMPOSITION FOR DESTROYING WATER-OIL EMULSIONS AND PROTECTING OIL-FIELD EQUIPMENT AGAINST CORROSION AND ASPHALTENE-TAR-PARAFFIN DEPOSITS

摘要

FIELD: oil and gas production.;SUBSTANCE: invention relates to pre-processing treatment of crude oil, in particular to dehydration and desalting of oil with the aid of surfactant additives. Composition of invention contains 15-17% glycerol-based ethylene oxide/propylene oxide block copolymer, 5-15% oxyethylated glycerol/toluene diisocyanate reaction product, additionally oxyethylated fatty acid-based amine ("Oksamin-15") or product of reaction thereof with phosphorus-containing compound ("Oksamin-F 15"), and solvent to 100%.;EFFECT: increased efficiency in protection of oil-field equipment against corrosion and asphaltene-tar-paraffin deposits and enabled and enabled simultaneous treatment of waste water.;2 tbl, 16 ex
