ASSESSMENT OF CORROSION DAMAGE TO OIL-WELL TUBING IN MINERAL ENVIRONMENTS

Abstract

The state of oil production technology and engineering, especially in the conditions of well operation with complex aggressive environment, requires solutions that allow to improve productivity processes without maximising costs. One of the reasons reducing effective well performance can be attributed to the formation of a corrosion layer formed on the surface of oilfield equipment. Mineral salts in formation waters together with other non-carbons form electrochemical corrosion activity on the surface structure of metal. As a result, there is a decrease in the strength of the metal of the tubing pipes in the well, the formation of cracks in the threads, as well as a decrease or complete loss of productivity. The effects of corrosion on pumping units can lead to emergency situations at oil production facilities. Currently, at the Kumkol oil field, the issue of increasing the strength of production equipment when working in conditions with high water content and mineral salt content in the composition has not lost its relevance. The purpose of this article is to determine a method for carrying out a set of anti-corrosion measures in the region with the destruction of metal tubing pipes and well pumps based on monitoring technological processes at oil enterprises.
