FIELD: oil production, particularly chemical means for preventing or limiting the deposition of paraffins or like substances in oil production equipment. ^ SUBSTANCE: composition includes surfactant, additive and solvent. Glycols and/or monoalkylphenyl polyethylene glycol esters are used as the surfactant. Polar electrolyte and acid amide are used as the additive. Above substances are taken in the following amounts (% by weight): glycols and/or monoalkylphenyl polyethylene glycol esters - 35-46, polar electrolyte and acid amide - 4-15, remainder is solvent. ^ EFFECT: prevention of asphalt-tar-paraffin deposit crystal growth by disintegration thereof and by hydrophilization of bottomhole equipment surfaces. ^ 1 ex, 3 tbl |
