摘　要
 讨论了胡状集胡五块油水井套管损坏的主要原因。套管损坏主要受地应力、固井质量、盐岩蠕变、射孔补孔、高压注水、强化采油、腐蚀及作业环境等因素的影响。提出了胡五块套管损坏防治方案。开发了高强度?准101.6mm(?准104.8mm)套管、高压注水套管保护工艺管柱、低伤害井下锚定工具、井下井况监测、井筒套管防腐、?准101.6mm套管延迟固井、开窗侧钻等系列防治技术，并进行了广泛的应用，取得了良好效果。

[Abstract] This paper discussed the main reason of casing damage for oil-water wells in block Hu 5.Casing damage is mainly influenced by many factors，such as the ground stress，well cementation quality，salty creep，perforation and re-perforation，high-pressure flooding，enhanced recovery，corrosion and operation environment. Therefore，casing damage preventing and controlling plan was proposed and a series of new preventing and controlling technologies were developed，such as high strength ?准101.6mm(?准104.8mm)casing，high-pressure flooding casing，protecting drilling strings，downhole anchoring tool with a low injury，well situation monitoring，casing anticorrosion，?准101.6mmcasing retarding cementation，casing sidetracking and so on.The technologies mentioned above were applied widely and the good effect was obtained.
