Oil pipeline leakage monitoring developments in China

Pipeline is the most economical and efficient way of oil transportation, pipeline integrity management is an effective means to prevent pipeline accidents and ensure the safe operation of pipelines economically and reasonably, timely and accurate pipeline leakage monitoring can greatly reduce the consequences of accidents, which is a crucial part of pipeline integrity management. Pipeline leakage monitoring in China has a long history, but there is no systematic summary. The monitoring methods for oil pipeline in China are reviewed and analyzed from the levels of national and industrial, by surveying the mileage of oil pipelines, leakage accidents, laws and regulations, and pipeline working conditions in recent years. The principles and research status of oil pipeline leakage monitoring methods are introduced in detail, and various methods are divided into hardware and software by the different acquisition and processing methods of leakage signals. Finally, the development trend of pipeline leakage monitoring method in the future is summarized and predicted: the combination of software and hardware, the efficient collection and processing of data, the intelligent analysis and diagnosis of working conditions, and the integration of information systems.
