FIELD: oil industry.
SUBSTANCE: invention relates to oil industry. Composition for asphaltene deposits removal, including a hydrocarbon fraction and a bottoms residue of butyl alcohols, contains a hydrocarbon fraction 85-163°C in the mixture with the bottoms of butyl alcohols produced at the following ratios, mass%: hydrocarbon fraction 85-163°C 50-80, bottoms of butyl alcohols 20-50, said mixture being subjected to a continuous wave action at a frequency of 7.2 kHz.
EFFECT: technical result is an increase in the dissolving power of the composition for the removal of asphaltene deposits in "harsh conditions", the expansion of the raw material base and cost reduction by eliminating the scarce additives that are the raw materials of petrochemicals.
