基于软件的输油气管道泄漏检测技术

对近年来国内外基于软件的输油气管道泄漏检测诊断技术进行了全面的总结与评述,对各种管道泄漏检测方法进行了11项指标性能的对比.认为输油管道的泄漏检测和定位技术已达到较高水平,应用效果良好,而输气管道的泄漏检测技术在微量泄漏与缓慢泄漏的检测灵敏度及定位精度方面还存在较大不足,指出这一领域应是当前的研究热点和发展方向.

Leak Detection and Location Methods of Software-based for Oil and Gas Transportation Pipelines

This paper summarizes and evaluates the primary methods of software-based approaches in detection and location of leakage for oil and gas pipelines developed in recent years. Eleven key attributes, such as sensitivity,location capability,assessment capability,response time,effectiveness,misalarming rate,maintenance requirement,suitability,prealarming capability and cost,for the leak detection methods of pipelines are compared. It is considered that the applied technology of leak detection and location has reached the advanced world level for oil pipeline, but for the gas pipeline the more improvement needs to do in the detection sensitivity and location accuracy of minor leakage and slow leakage. It is pointed out that this field should be a key research point.
