FIELD: petroleum industry.
SUBSTANCE: invention relates to the field of petroleum production and can be used for processing petroleum boreholes, processing pipelines for in-field petroleum collection and transportation, processing bottom-hole areas of borehole formations to reduce the viscosity of rheologically complex petroleum. The hydrocarbon solvent includes, wt.%: toluene of petroleum grade A 15 to 25; winter or arctic diesel fuel 5 to 15; natural gas condensate 65 to 75. Natural gas condensate is produced during purification of the pipeline compression products, including steam heating the pipeline compression products to a temperature of 62 to 63°C, cooling, followed by separating.
EFFECT: reduction in the solidification temperature of the hydrocarbon solvent with the maintained effectiveness of dissolution of ARPD asphaltene-resin-paraffin deposition.
