| 摘 要： | 焊缝疲劳开裂是钻井隔水管常见的失效形式。海洋钻井隔水管全尺寸疲劳试验是评价和验证其疲劳性能的唯一方式,国内在这方面的研究还比较少。对海洋钻井隔水管疲劳试验方法、疲劳设计和评价标准、S-N曲线选取、试件设计、试验样本数的选取进行了研究,为钻井隔水管的疲劳性能试验研究及评价提供参考。提出了提高海洋钻井隔水管疲劳寿命的方法。

| Abstract: | Weld fatigue cracking is a common failure mode of drilling riser. Full-scale fatigue test of Marine riser is the only way to evaluate and verify its fatigue performance. The fatigue test methods, fatigue design and evaluation criteria, S-N curve selection, specimen design and sample number selection of offshore drilling risers were studied, which could provide reference for the fatigue performance test research and evaluation of drilling risers. The method to improve the fatigue life of offshore drilling risers was proposed. |
