| 摘 要： | 将注汽热采井井筒温度场传输到井筒应力模型中 ,用有限元软件ANSYS进行了计算。计算结果表明 ,使用常温套管弹性模量对套管极限温度载荷进行计算 ,所得极限温度比实际极限温度要低 ,因此能提高设计结果的安全性。增大水泥高温热膨胀系数有利于保护套管和水泥环。

| Abstract: | The temperature field of the steam injection well is inputted into the stress field model of the steam injection well. The stress field is calculated by using software package ANSYS. The calculated temperature limit is lower than virtual temperature limit when elastic modulus at normal temperature is used in calculation of temperature limit. Increase of the expansion factor of cement is an aid to protect casing and cement ring |
