Hydrophobic interactions in adsorption layers of nonionic and anionic SAS and their influence on technological indicators of drilling fluids

During drilling, an important role is played by the ability of the used inhibiting, lubricating and other additives to drilling fluids to form dense, saturated adsorption layers (adlayers) on the contact surfaces. Of significant importance in the formation of saturated adlayers is the ability of hydrocarbon radicals of adsorbed SAS molecules to hydrophobic interactions, which lead to deeper lyophobization of the surface, providing high technological parameters of the drilling fluid.
