Abstract
Изобретение касаетс защиты металла от коррозии и может быть использовано в нефте- и газодобывающей промышленности . Ингибитор содержит, триа килбензил- метиламмоний хлористый, или фтористый, или подистый 5-95; октадециламин-1-5; хи- нолин или его производные / -хинолин или 2,3-диметилбензо (h) хинолин 4-86. Повышение эффективности защиты от сероводородной к оррозии и наводороживани и улучшение реологических свойств нефти достигаетс за счет дополнительного введени октадециламина и хинолина или его производных. 1 з.п.ф-лы, 3 табл.The invention relates to the protection of metal against corrosion and can be used in the oil and gas industry. The inhibitor contains, trikylbenzylmethylammonium chloride, or fluoride, or podisty 5-95; octadecylamine-1-5; quinoline or its derivatives / -quinoline or 2,3-dimethylbenzo (h) quinoline 4-86. An increase in the effectiveness of protection against hydrogen sulfide towards orgasy and hydrogenation and improvement of the rheological properties of oil is achieved by additionally introducing octadecylamine and quinoline or its derivatives. 1 hp ff, 3 tab.
Description
Изобретение относитс к защите металла от коррозии и может быть использовано в нефте- и газодобывающей промышленности .The invention relates to the protection of metal against corrosion and can be used in the oil and gas industry.
Цель изобретени - повышение эффективности защиты от сероводородной корро- и наводороживани . и улучшение реологических свойств нефти.The purpose of the invention is to increase the effectiveness of protection against hydrogen sulfide corrosion and hydrogenation. and improving the rheological properties of petroleum.
Ингибитор готовили механическим смешением компонентов.The inhibitor was prepared by mechanical mixing of the components.
В качестве агрессивной средь использовали модельную среду NACE и пластовые воды месторождений Л льмикар и Коштар с содержанием сероводорода 600 мг/л. Эффективность защиты от сероводородной коррозии оценивали на образцах.стали 17Г1С, эффективность защиты от наводороживани - на пластинчатых образцах стали У9А.As an aggressive medium, NACE model media and formation waters of the Lmikar and Koshtar deposits with hydrogen sulfide content of 600 mg / l were used. The effectiveness of protection against hydrogen sulfide corrosion was evaluated on samples of steel 17G1S, the effectiveness of protection against hydrogenation on plate samples of steel U9A.
Состав ингибитора коррозии приведен в табл.1, результаты коррозионных испытаний - в табл,2.The composition of the corrosion inhibitor is given in table 1, the results of corrosion tests in table 2.
В табл.3 приведены величины динамической в зкости сернистой нефти Коштар- ского месторождени в зависимости от состава и количества вводимого ингибитора ./.Table 3 shows the values of the dynamic viscosity of the sulfurous oil of the Koshtar oil field depending on the composition and amount of the inhibitor added. /.
Технико-экономическими преимуществами ингибитора вл етс повышение эффективности защиты от сероводородной коррозии и наводороживани и улучшение реологических свойств нефти.The technical and economic advantages of an inhibitor are to increase the effectiveness of protection against hydrogen sulfide corrosion and hydrogenation and improve the rheological properties of oil.
