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 before transferring it into collection and transportation system for paraffin-rich oils. Invention provides for preparation of efficient formulation , which contains 20-75% of glycerol-based ethylene oxide/propylene oxide block copolymer, 2-10% of nonionic surfactant ("Dossolvan"), additionally 4-20% of product obtained by reaction of above block copolymer with toluene diisocyanate, 0.5-2.5% of 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 to remove oil derivatives.;2 tbl, 16 ex
