FIELD: oil industry.
SUBSTANCE: invention relates to an aqueous pour point depressant dispersion composition for improving fluidity of crude oil at low temperatures. Composition contains an ethylene vinyl acetate copolymer, a dispersing agent, water and optionally an aqueous pour point depressant.
EFFECT: obtained pour point depressant lowers setting point of crude oil, exists in liquid state in a wide temperature range and demonstrates long-term resistance to creaming.
