- 摘要:
- CNG地下储气井是目前国内CNG加气站广泛使用的高压储气方式，其安全性是加气站安全运行的关键。应用ANSYS有限元软件对Φ1778×10.36标准储气井的套管和管箍进行应力分析和疲劳分析，对于CNG地下储气井的安全运行有参考意义。
At present, underground CNG (Compressed Natural Gas) storages are widely applied for high pressure gas storage at CNG filling stations inChinaand their safety is the key for assuring their normal operation. ANSYS is applied to carry out stress analysis and fatigue analysis on casings and pipe clamps in the standard underground CNG storage and the analysis conclusion provides theory support to proper operation of other underground CNG storages.
