FIELD: oil and gas production.
SUBSTANCE: invention refers to composition containing non-ionic demulsifying agent, additive and solvent, which contains as non-ionic demulsifying agent block copolymer of ethylene and propylene oxides on base of monoethyleneglycol with molecular weight 4300 or block copolymer of ethylene and propylene oxides on base of monoethyleneglycol with molecular weight 10000, or block of copolymer of ethylene and propylene oxides on base of glycerine with molecular weight 6000, or block of copolymer of ethylene and propylene oxides on base of glycerine with molecular weight 5000; as additive polyalkylbenzol resin is taken, wt %: said block copolymer of ethylene and propylene - 25.0-40.0, polyalkylbenzol resin - 10.0-25.0, solvent - the rest.
EFFECT: dehydration and regulation of rheological properties of high viscous oil and water-oil emulsions.
