FIELD: petroleum industry.
SUBSTANCE: invention relates to the petroleum industry, particularly, to compositions for removing asphaltene-resin-paraffin deposition (ARPD). The composition for removing asphaltene-resin-paraffin deposition is comprised of an industrial solvent constituting a benzene-containing fraction produced in the process of catalytic reforming, with the aromatic fraction content of 20%, toluene, a surface-active agent - the product "Amdor-IK-AF" consisting of 100% 2-alkylimidazoline, at the following ratio of components, % vol.: industrial solvent 80 to 90; toluene 9 to 19.9; the product "Amdor-IK-AF" 0.1 to 1.0.
EFFECT: high dissolving and dispersing capacity relative to solid deposits, effective removal of high-melt ARPD from the surface of oilfield equipment and in boreholes with simultaneous prevention of corrosion processes on the surface of the oilfield equipment.
