| 摘 要： | 抗挤毁性能是油套管的一项至关重要的性能指标。椭圆度和厚不均是存在于不同套管中的初始微小身体缺陷，运用Ｋｏｉｔｅｒ初始后屈服理论分析承受均匀外压力的长薄油套管的后屈曲性态及其缺陷敏感性，得出承受均匀外压力的长薄壁油磁管具有后屈曲稳定性的结论。

| Abstract: | Koiter's Initial Postbuckling Theory is applied to analyse the long thin-walled casing under uniform external pressure, from which it is concluded that the long thin-walled casing under uniform external pressure owns postbuckling stablity. |

| Keywords: | casing collapse initial postbuckling |
