The paper studies the physicochemical properties of import-substituted and export-oriented nitrogen, amine and phosphorus new composite inhibitors for corrosion protection of steels as well as scaling obtained from local raw materials and industrial wastes. Inhibiting properties of corrosion and mineral salt deposit accumulation in acid and hydrogen sulfide environments have been determined. It was found that the efficiency of the inhibition process with the use of composite inhibitors in acidic and hydrogen sulfide environments obeys the Langmuir law. The values of activation energy of the adsorption process in these media and thermodynamic values (∆H, ∆S, ∆G).
Currently, the Republic of Uzbekistan deservedly pays attention to the introduction of inhibitors to protect equipment from corrosion and scaling in production. The use of inhibitors allows several times to increase the service life of expensive equipment. In this regard, the most effective inhibitors of neutral and slightly alkaline media are nitrogen, amine and oxygen-containing organic compounds [1-3] as well as zinc organophosphonic acids, which effectively prevent corrosion and deposits of mineral salts on the surface of equipment.
The article presents the ways of improvement and development new weighted mud receipt based on composite lubricant from local raw materials and industrial wastes for drilling oil and gas wells. In the process of building oil and gas wells to maintain the stability of the walls, to prevent the flow of salts, and to prevent the penetration of formation fluids into the well, it becomes necessary to increase the density of the drilling fluid, which can be accomplished by introducing components with increased density.
