海底管道内腐蚀监测技术研究现状与发展

Progress in Corrosion Monitoring Technology in Submarine Pipeline

海底管道(以下简称海管)一旦发生泄漏事故,不但会造成石油开采平台生产停滞、产生巨大的经济损失,而且会造成严重的海洋生态污染,带来严重的社会影响。对海管的内腐蚀情况进行监测,及时发现潜在的失效风险,具有重要意义。本文总结了内腐蚀监测技术的分类、原理、特点和研究现状,指出了海管内腐蚀监测技术未来发展方向是无损检测技术与腐蚀在线监测技术融合应用、高海洋环境适用性和数字化远程管理。

The submarine pipeline failure accident will not only cause production stagnation with huge economic losses, but also result in serious ocean pollution and environmental problem.It is of great significance to monitor the internal corrosion of submarine pipeline and discover the potential failure risk in time. This paper summarizes the classification, principle, characteristics and research status of internal corrosion monitoring technology, and points out the future development direction of offshore pipeline internal corrosion monitoring technology: the integrated application of nondestructive testing technology and corrosion online monitoring technology, high applicability to marine environment and digital remote management.
