摘要
在分析连续油管应力要素的基础上，应用弹塑性屈服条件，提出了连续油管屈服极限的数学模型，并据此计算及绘出了连续油管的屈服极限曲线，得出了一些对连续油管的应用有重要参考意义的结论。
After analyzing the stress factors of coiled tubings, by using the elastic and plastic yield conditions, the authors present a mathematical model for the yield limits of coiled tubings,work out thereby the curve of the yield limits. and draw conclusions of great importance to the application of coiled tubings.
