FIELD: chemistry.
SUBSTANCE: invention relates to compositions for inhibiting formation of gas hydrates in different hydrocarbon-containing liquids and gases containing hydrate-forming agents and water, and can be used in processes of extraction, processing and transportation of hydrocarbon raw material to prevent formation of gas hydrates. Composition contains a kinetic inhibitor, thermodynamic inhibitor and synergetic additive selected from a group comprising quaternary ammonium salts, ethylene glycol esters of general formula R1OCH2CH2OR2, where R1 is a hydrogen atom or alkyl radical, R2 is an alkyl radical, oxyethylated fatty alcohols, oxypropylated fatty alcohols, polyethylene oxide, polypropylene oxide, copolymers of ethylene oxide and propylene oxide or a mixture of said substances in following ratio of components, wt%: kinetic hydrate formation inhibitor 2.0-8.0; thermodynamic hydrate formation inhibitor 84.0-96.0; synergetic additive - balance.
EFFECT: higher inhibiting capacity.
