Исследования поверхностной и адсорбционной активности модифицированного лигносульфонатного реагента для регулирования параметров бурового раствора

Abstract

The possibility of obtaining a modified lignosulfonate reagent based on acrylic and lignosulfonate components is considered. To study the effect of electrolytes on the surface activity of a complex reagent based on acrylic and lignosulfonate components, the surface tension of aqueous solutions of inorganic salts of NaCl and CaCl2 of different concentrations was determinedwith the introduction of 0.1 to 2% of the reagent. The assessment of adsorption activity was carried out on the basis of constructingan isotherm of surface tension at the liquid-liquid interface under static conditions in time at a constant concentrationof the reagent. The possibility of a modified lignosulfonate reagent to effectively reduce the conditional viscosity of clay drilling mud in the temperature range from 20 to 180°C has been established.
