| 摘 要： | 连续油管工作寿命是短是影响连续油管作业成本的主要因素之一，以疲劳强度理论和塑性力学为基础，探讨连续油管在反复卷绕弯曲条件下的疲劳寿命问题，给出连续油管卷绕弯曲疲劳寿命计算方法，并讨论卷绕滚筒半径和油管尺寸对连续油管寿命的影响，分析表明，连续油管卷绕曲疲劳属于低周疲劳问题，疲劳寿命较短；改进边疆油管作业装置的结构，不同导向架是延长连续油管使用时间的有效途径。

| Abstract: | Coiled tubing(CT) life is very short,which is main fact to affect cost of CT services.Based on theory of fatigue strength and plasticity,coiled-tubing-life is analysed when coiled tubing is bent,and CT life affected by reel radius and coiled tubing size discussed.The result shows that because life analysis of bending coiled tubing is a fatigue problem with fewer cycles,coiled tubing life is not long.In order to increase coiled tubing work time,the structure in coiled tubing system is improved without gooseneck. |
