With the growth of global energy demand,the effective development of oil resources has become particularly important.In the long-term production process,oil wells will face various problems such as casing damage,corrosion,cracks,etc.These problems not only affect the normal production and economic benefits of oil wells,but also may cause environmental pollution.In order to solve these problems and improve the safety and production efficiency of oil wells,casing subsidy technology has emerged.It summarizes the types of casing subsidies,the application of casing subsidy technology,the challenges faced,and future prospects.By analyzing practical cases of multiple oil fields at home and abroad,It explores the role of this technology in improving oil field development efficiency,extending the service life of oil wells,and proposes future research directions and technical improvement suggestions.
