摘　　要：本文对近年在储气井检验中发现的主要问题和案例进行了统计,对每一种案例进行了讨论,分析了缺陷形成原因,并提出了相应的处理方式和检验要点。统计表明腐蚀减薄是储气井最常见的失效形式,腐蚀缺陷应作为储气井检验的重点。在没有其它螺纹连接性能检验方法的情况下,耐压试验应作为储气井定期检验的必检项目。The main periodical inspection cases of gas storage well（GSW） in recent years are statistical analyzed. Each type of cases of GSW is discussed, including the reason of defects forming, and then the key inspection points and the treatment methods are proposed. From the statistical analysis, the corrosion thinning is the most popular failure mode for GSW in service. And the corrosion defects inspection should be considered the most important in periodical inspection. When no other inspection method for thread connection, the hydraulic test is the unique way to check the thread connection and must be carried out in periodical inspection.
