Composite salt drilling fluid to drill tool corrosion analysis and control measures
This paper mainly discusses the composite salt drilling fluid on drill tool corrosion and control measures.First,the composition and chemical property characteristics of the composite salt drilling fluid and the mechanism of drilling tool corrosion were analyzed,including electrochemical corrosion,corrosion parameters and corrosion under special environmental conditions.In the light of these problems,the corresponding control countermeasures are put forward,including strengthening the selection of materials and surface technology,optimizing the parameters of composite salt drilling fluid,and strengthening the technical management and control measures,so as to reduce the corrosion rate of drilling tools,improve the efficiency and safety of drilling operations.
