petroleum industry, more particularly prevention of formation of asphalt-resin-paraffin depositions in oil field equipment during production, collection and transportation of petroleum. SUBSTANCE: paraffin deposition inhibitor comprises oxyethylated alkyl phenols, additive and aromatic solvent. Oxyethylated alkyl phenols include compound of general formula I: C9-12H19-25 C6H4(OC2H4)xOH wherein X is 4-12, and additive includes sulfonated adducts of general formula II: R1SO-mK+ wherein . Solvent is aromatic solvent; e.g. butylbenzene fraction, styrene production by-product or light pyrolysis resin. Ratios of said reagents are as follows wt %: oxyethylated monoalkyl phenyls of formula I, 3-7; sulfonated adducts of formula II, 12-24, and aromatic solvent, the balance. EFFECT: increased efficiency of paraffin deposition inhibitor. 1 tbl
