The low-viscosity hydrocarbon base is a mixture of distillate oil with distillates and contains a special distinctive agent. Low-viscosity hydrocarbon base can be used as a dispersion medium for drilling fluids used in drilling wells in complicated conditions. The base provides good lubricating and anti-corrosion properties for drilling tools; high quality of the opening of productive layers; high stability of the solution to the aggressive effects of salts, hydrogen sulfide, carbon dioxide and stable rheological properties regardless of temperature.
