再通过合理的假设，建立用于计算直径增长的计算机逻辑框图。

Then, a logic computational diagram is constructed for calculating diametral growth by assuming fatigue cyclic softening, namely yield strength reduction as tubing fatigues.

这些分析将帮助用户在连续油管发生严重损坏之前， 提前诊断连续油管的直径增长， 并排除或减少引起直径增长的因素。

These analyses will help operators detect early CT diametral growth before severe damage occurs, and eliminate or reduce operational factors that contribute to growth.

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.
