摘要
管道的泄漏检测特别是气体管道的泄漏检测一直是热点和难点,对于含硫气田,管道的泄漏检测尤为重要。介绍了分布式光纤温度检测(DTS)技术的特点、基本原理及理论计算,结合具体的应用案例分析了光纤泄漏检测系统的特点,并对管道泄漏检测常用的各种方法进行了比较筛选,指出了分布式光纤温度检测技术的优势以及存在的不足。
The leakage detection of pipeline, especially gas pipeline is the most focal and difficult issue. For sulfur contained oil-gas field, the pipeline leakage detection is of great importance. The character, basic theory and theoretical calculation of distributed fiber temperature sensor （DTS） technology are introduced. The specialty of fiber leakage detection system is analysised together with the detailed application case. Combining with the character and requirement of sulfur contained oil-gas field, various methods for pipeline leakage detection are introduced and compared, and the advantages and disadvantages of distributed fiber temperature detection technology are listed.
