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

Abstract

At present, the issue of improving the stability of production equipment due to high water cut of well products and the impact of mineral salt deposits contained in it at local oil fields Kumkol and others has not lost its relevance. The article discusses the mechanism of corrosion destruction of metal tubing pipes and well pumps in the oil and gas industry, i.e. it contains information about the initial development of corrosion during operation. One of the main problems encountered in oil fields is studied with regard to the effect of the chemical composition in layered water on tubing and hence corrosion. Experimental studies are performed here with respect to iron sulphide formation in downhole underground equipment. According to the nature of performance of underground production equipment, the value of corrosion rate of steel materials is determined. Graphical treatments of the average surface fluid result at the depth of the borehole of the required size are carried out. In this regard, based on the control of technological processes, the purpose of introducing a system for measuring and diagnosing the development of corrosion on downhole equipment, as well as the effective implementation of a set of anti-corrosion measures on oilfield equipment and pipelines is determined.
