FIELD: chemistry.
SUBSTANCE: invention relates to a composition containing a glycerine-based block-copolymer of ethylene and propylene oxides (5.0-15.0 wt %), an ethylenediamine-based block-copolymer of ethylene and propylene oxides (25.0-70.0 wt %), tetrahydro-1,4-oxazine (0.1-0.35 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 methanol and fresh water (the balance).
EFFECT: faster and complete breakdown of emulsions with simultaneous protection of oil field equipment from corrosion.
