摘要
管道泄漏检测可为管道运行安全提供重要保证。总结国内外陆地和海底管道的泄漏检测方法。由于现场情况复杂,采用单一方法进行泄漏检测并不能得到满意的结果,尤其是海底管道,因此需要多种方法结合使用。对基于外部和内部检测的各种方法的原理、优缺点、应用情况(陆地/海底,单相/多相等)等做了介绍。对敏感性、稳定性、实时性以及泄漏反应时间等做了对比。为管道泄漏检测的研究提供参考。
Pipeline leak detection is the important safeguard to the operation of pipelines.The domestic and international pipeline leak detection methods,including terrestrial and submarine pipelines are summarized.Due to the complexity of the situation,especially to subsea pipeline,a single method of leak detection does not get satisfactory results.So a variety of methods need to be combined.Detection methods based on external and internal detection are provided,including principles of each method,advantages,disadvantages and applications（land/subsea,single-phase/multiphase）,etc.These methods about sensitivity,stability,realtime and leakage of reaction time and so on are compared.It provide reference for research of pipeline leak detection.
