COMPOSITION FOR BREAKING DOWN WATER-OIL EMULSIONS AND PROTECTING OIL FIELD EQUIPMENT FROM CORROSION

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a composition containing a glycerine-based block-copolymer of ethylene and propylene oxides (15.0-50.0 wt %), an ethylenediamine-based block-copolymer of ethylene and propylene oxides (15.0-50.0 wt %), a condensation product of oxyethylated nonylphenol with a different oxyethylation degree with polyoxymethylene and a carbonic acid diamide (1.0-5.0 wt %), a mixture of oxyethylated nonylphenol and a triethanolamine salt of a sulphoethoxylate of oxyethylated nonylphenol (1.0-5.0 wt %), a water-alcohol solution of alkyl phosphates (1.0-5.0 wt %) in a solvent - mixture of nefras with methanol or methanol and fresh water (the balance).;EFFECT: faster and complete breakdown of emulsions with simultaneous protection of oil field equipment from corrosion.;4 tbl, 5 ex
