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.
