FIELD: mining.
SUBSTANCE: in method of preparing flushing solutions on oil base for pumping into well including introduction of liquid hydrocarbon slurry oil into oil products as hydrocarbon slurry oil there is used oil paraffin dissolvent at amount of 5-20 volume % with addition of synthetic rubber SCD-N at amount of 0.01-0.05 wt %.
EFFECT: increased efficiency of pumping flush solutions on oil base through flow string at repair operations at well and at transporting oil of high viscosity via pipeline by means of reducing hydraulic resistance due to simultaneous reduction of fluid viscosity and turbulence.
