| Abstract: | An analysis of reasons for casing damage encountered in our fields is carried out. It is believed that the casing damage is mainly due to physical, chemical and human factors. Among them, the damage due to physical results from formation stress and external force exerted on casing; chemical damage from corrosion is in the process of casing's idle and use, and human factor involves incorrect design, manufacturing and operation. |
