DEVELOPMENT AND APPLICATION OF NEW COMPOSITIONS TO IMPROVE THE EFFICIENCY OF OIL FIELD EQUIPMENT OPERATION

Abstract

One of the urgent problems in the oil industry is the reliable protection of oil field equipment from corrosion. With this in mind, as a result of laboratory studies, three compositions were developed based on phospholipids, fatty acids, phosphoric acid, nitrogen compounds, asidol, naphthenic acids and light gas oil. The complexity of the composition gives the resulting compositions multifunctionality and allows them to be used in various aggressive conditions. In laboratory conditions, the effect of these compositions on the corrosion rate of metals and on the vital activity of sulfate reducing bacteria (SVB) was studied. Based on the obtained results, the concentration of the compositions (500 mg/l) was established, providing a protective effect against corrosion, which was 94–95 %, and the degree of suppression of SVB was 97–99 %. Field tests of corrosion inhibitors also yielded positive results: the protective effect against corrosion was 89–90 %, and the degree of SVB suppression was 92–97 %.
