Abstract
Background This article is devoted to the study and analysis of the main causes of the occurrence of biological corrosion processes at the objects of the oil industry complex, as well as to the study of the effectiveness of the use of new chemical reagents as bactericides and corrosion inhibitors. Aims and Objectives Investigation of the biocontamination of sulphate-reducing bacteria (SRB) of high-sulfur oils, as well as soil samples taken in the immediate vicinity of the pipeline break site and along its route. Results The results of evaluating the effectiveness of the use of the chemical reagent catamine AB for anticorrosion protection of oilfield equipment and pipelines are presented. It has been shown that catamine AB has a high bactericidal activity against both SRB and pseudomonads. It has been found that this reagent at a concentration of 100-150 mg/dm3 effectively suppresses corrosion processes, providing high protection of metals from destruction. The use of this reagent to protect metal structures from biological corrosion processes will significantly reduce the number of accidents, increase reliability and increase the uptime of technological equipment and main pipelines.
