| Summary: | The article studies the physical and chemical properties of water glycerin to obtain various types of surface-active substances for use as additives to boring solutions. The addition of technical glycerin to the composition of surface-active substances obtained from raw fatty acids of cotton soap stock at oil and fat enterprises contributes to a significant improvement in their surface-active properties. A water solution of glycerin to a certain extent increases the surface-active properties of the developed soap-like surface-active substances. The qualitative indicators of the composition of surfactants obtained with different ratios of a water solution of glycerol of liquid and ointment fractions of raw fatty acids of cotton soap stock were studied for their use in the process of drilling oil and gas wells. Analyzes of the developed compositions of were carried out in the preparation of drilling fluids from alkaline bentonite, alkaline earth bentonite and carbonate palygorskite, as well as double and triple compositions. A comparative analysis of the main indicators of drilling fluids, as well as surface-active substances synthesized from the greasy fraction of raw fatty acids of cotton soap stock, showed the greatest stability of boring solutions at high temperatures and salinity of formation waters.
