FIELD: lubricants and boring engineering.
SUBSTANCE: multiple-purpose reagent containing lubrication-and-stabilization component (70-80%) and solvent (20-30%) contains, as said lubrication-and-stabilization component, oxidized mixture of paraffins, naphthenic and aromatic hydrocarbons at ratio 2:3:4, and, as said solvent, diesel fuel or kerosene.
EFFECT: improved lubrication properties of viscous-plastic drilling fluids and stabilized inverted emulsions used in boring operation and in pullout of hole.
