| 摘 要： | 非黏结柔性管道是海洋油气开发的重要装备，在海水环境中，抗拉铠装层发生腐蚀会对安全运行产生严重威胁，因此明确抗拉铠装层腐蚀机理、对柔性管道的检测和对抗拉铠装层的腐蚀评估十分重要。抗拉铠装层腐蚀与环空的气体环境和水环境有关，采用合适的检测方法和设备检测环空，可以帮助判断其腐蚀情况，并为腐蚀疲劳寿命评估和应对策略制定提供参考。针对抗拉铠装层腐蚀机理、非黏结柔性管道检测、腐蚀疲劳寿命评估和腐蚀应对措施进行了总结，指出机理研究和检测评估方法的不足，为国内柔性管道抗拉铠装层腐蚀研究和完整性管理提供参考。

| Abstract: | Unbonded flexible pipeline is an important equipment for offshore oil and gas development. In seawater environment, the corrosion of tensile armor layer will pose a serious threat to safe operation. Therefore, it is very important to detect the flexible pipe, clarify the corrosion mechanism and evaluate the corrosion of tensile armor layer. The corrosion of the tensile armor layer is related to the gas and water environment of the annulus. So appropriate detection methods and equipment to detect the annulus are necessary. This can help determine the corrosion situation and provide a reference for corrosion fatigue life assessment and strategy formulation. Based on the above, the corrosion mechanism of tensile armor layer, detection of unbonded flexible pipe, evaluation of corrosion fatigue life and corrosion countermeasures are summarized. The shortcomings of mechanism research and detection evaluation methods are pointed out. The work will provide reference for the research and integrity management of tensile armor layer corrosion of flexible pipes in China. |
