FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method for preparation of heavy oil to processing, including emulsification of oil product by intense cavitation action. Before emulsification, heavy oil is treated in a magnetic field using neodymium magnets to reduce viscosity, and then treated oil is mixed with light oil to concentration of heavy oil in mixture of 7 to 9 %, then produced mixture is subjected to cavitation treatment with subsequent atmospheric distillation.
EFFECT: increased yield of light fractions when processing heavy oil from 5 to 7 %.
