摘　　要：四川盆地2/3的气田含有硫化氢等酸性气体,造成管道内部出现了氢鼓泡、氢致开裂、应力腐蚀开裂、硫化物应力开裂等腐蚀形貌,导致管道快速穿孔,增加管道事故的风险。为了及时掌握管道内壁的运行状况,保障管道本质安全,应定期对高含硫天然气管道开展检测。本文介绍了漏磁、超声波、电磁超声、涡流、射线五种检测技术的优缺点和适用范围,并展示了其中三种方法的现场检测结果,对比分析了几种方法的灵敏度和准确性,为高含硫天然气管道的完整性评价提供强有力的数据支撑;最后基于高含硫天然气管道的特点,对管道材质的选择、无损检测技术的发展及应用进行了展望。Two-thirds of the gas fields in the Sichuan Basin contain acidic gases such as hydrogen sulfide,which causes corrosion morphology such as hydrogen bubbling,hydrogen induced cracking,stress corrosion cracking,and sulfide stress cracking inside pipelines,resulting in rapid pipeline perforation and an increased risk of pipeline accidents.Regular inspections of high sulfurnatural gas pipelines should be performed to ensure the inherent safety of the pipeline and to obtain a timely understanding of the operation status of the pipeline's inner wall.This summary discusses the benefits,drawbacks,and applications of five detection techniques:magnetic flux leakage,ultrasonic testing,electromagnetic acoustic transducers,eddy current testing,radiographic testing.Additionally,the on-site detection findings of three methods were presented,and the sensitivity and accuracy of several approaches were compared and assessed,providing solid data support for the integrity evaluation of high sulfur natural gas pipelines.Finally,based on the features of high sulfur natural gas pipelines,the selection of pipeline materials and the use of non-destructive testing techniques were addressed.
