摘要
简述了油气长输管道泄漏的原因和危害;回顾了国内外油气长输管道泄漏检测技术发展的历史;详细介绍了热红外线成像、探地雷达、气体成像、传感器法、探测球法、半渗透检测管检漏法、GPS时间标签法、压力波法、小波变换法、相关分析法、状态估计法、系统辨识法、神经网络法和统计检漏法等20多种管道泄漏检测技术方法,以及泄漏检测方法的诊断性能指标和综合性能指标;指出了现在存在的问题和发展的趋势。
Described are causes and harms of leakage in long distance oil and gas pipelines. Reviewed is development in inspection techniques for leakage in long distance oil and gas pipelines. Introduced are more than 20 leakage inspection methods, such as hot infrared ray imaging method, ground detection radar method, gas imaging method, sensor method, relative analysis method, state estimation method, system identification method, statistic leakage inspection method. Described are diagnosis performance index and comprehensive performance index and pointed out are some problems at present and development tendency.
