Abstract
It is well known that in oil-producing countries with advanced industrial development, one of the most pressing unresolved challenges is protecting the internal surfaces of equipment and facilities from the effects of aggressive corrosive environments, thereby extending their operational life. Based on this, the present article explores the results of numerous laboratory tests on the effects of the newly developed organic MARZA-4 reagent and a composition provisionally named HAK-2 against hydrogen sulfide, carbon dioxide, and sulfate-reducing bacteria, which are primary causes of internal surface corrosion in the oil industry. For the first time, the MARZA-4 reagent was studied for its effectiveness against sulfate-reducing bacteria in aggressive corrosive environments such as neutral, acidic, and alkaline media, as well as in the “Postgate-B” nutrient medium. It was determined that the MARZA-4 reagent possesses bactericidal-inhibitor properties at an optimal concentration of 20 mg/L. At this concentration, its corrosion protective effect in neutral, acidic, and alkaline environments was found to be 98%, 98%, and 94%, respectively. In the “Postgate-B” nutrient medium, the bactericidal effect against Desulfovibrio desulfuricans and Desulfomicrobium cells was 78% and 81%, respectively.
