- Modelling the diametral growth of coiled tubing under the action of an internal pressure. 连续油管在内压作用下直径增长模型的建立。
- This new model shall provide an effective tool both in understanding the mechanism of the CT ballooning and for accurately predicting the CT diametral growth. 这一模型将为理解连续油管鼓胀的机理以及准确预测连续油管直径增长提供一个有效的工具。
- The model results show that when the CT is cycled under the action of an internal pressure, fatigue cyclic softening inevitably leads to the diametral growth. 理论模型计算结果表明,当连续油管在内压下循环弯曲时,疲劳循环屈服强度衰减不可避免地导致直径增长。
