油气管道泄漏检测技术发展现状

Present State of the Development of Oil-gas Pipelines Leak-detection Technologies

简单说明了油气长输管道泄漏的原因和泄漏的危害,详细介绍了声发射技术法、GPS时间标签法、负压波法、压力点分析法、压力梯度法、状态估计法、神经网络法和统计检漏法等几种管道泄漏检测技术方法,最后指出了存在的问题和发展的趋势。

It briefly explain the reasons for the leakage of oil and gas pipelines and danger of leakage,and makes a detailed account of several pipeline leak detection methods like the acoustic emission technique,GPS labeling,negative pressure wave,pressure wave,state estimation,neural networks and statistical detection method,etc,pointing out the existing problems and the developmeatal trend.
