研究了连续油管的工作力学特性，建立了连续油管弯曲、抗内压强度和外部挤毁压力、直径增长、纵向伸长及卡点位置分析计算模型。
Mechanical characteristic of ct is studied. The model of bending, internal pressure strength and external collapse strength, diametric growth and stuck-point of ct is established.
该方法将有限元计算与应变检测结合起来，大大提高了有限元计算的精度，对预测套管的挤毁压力、指导高抗挤套管的开发具有一定的参考价值。
Then the improved model is used to calculate the final casing collapse strength. This method combines FEA and strain test together and thus can get more …
计算表明，在非均布外挤压力作用下，套管抗挤毁强度大大降低。
Calculation shows that the casing collapse resistance decreases greatly under nonuniform loads.
