(ASSESSMENT OF THE FEASIBILITY OF USING PROTECTIVE POLYMER COATINGS ON TUBING TO PREVENT INORGANIC SCALE DEPOSITS IN THE TUBING)
В статье предложен метод, позволяющий оценивать способность защитных покрытий противостоять образованию неорганических солей на внутренней поверхности насосно-компрессорных труб. Предлагаемый метод оценки позволяет принять обоснованное решение о целесообразности применения внутренних защитных покрытий насосно-компрессорных труб для профилактики предотвращения (или снижения) образования неорганических солеотложений. Рассмотрены конструктивные особенности испытательного стенда оценки стойкости покрытий к неорганическим солеотложениям, позволяющего моделировать условия образования солеотложений, максимально приближенные к реальным условиям объектов нефтедобычи. Представлены результаты стендовых испытаний трех образцов покрытий и одного образца из стали марки Ст 40Г2. Отмечено, что в целях оценки эффективности применения насосно-компрессорных труб с внутренним антикоррозионным покрытием в качестве меры борьбы с солеотложениями требуется проведение дополнительных исследований.
The paper proposes a method for assessing the ability of protective coatings to resist the formation of inorganic salts on the inner surface of tubing. The proposed evaluation method allows making an informed decision on the expediency of applying internal protective coatings of tubing to prevent (or reduce) the formation of inorganic salt deposits. The paper considers the design features of the coating inorganic fouling resistance estimation test bench allowing simulation of fouling formation conditions close to real oil production facilities. The results of bench tests of three coating samples and one sample of St 40G2 steel grade are presented. It is noted that in order to assess the effectiveness of the use of tubing with internal anticorrosion coating as a measure to combat scale deposits, additional research is required.
