长输油气管道泄漏检测技术综述

RESEARCHES ON PIPELINE LEAK DETETION METHODS

随着石油、天然气工业的不断发展 ,管道输送在国民经济中地位越来越重要。长输管道在运行中的泄漏既造成资源的损失 ,也污染了环境 ,是一个急需解决的问题。本文介绍了长输管道泄漏检测技术的现状 ,指出以软件为基础的实时瞬变模型法和统计决策方法以及光纤传感器泄漏检测方法有着良好的发展前景。

With development of oil and natural gas industry, pipeline transportat ion has played a more important role in national economy. Pipeline leak can lead up to resource loss and environment pollution. It is necessary to resolve those problems as soon as possible. The actuality of leak detection methods is discus sed in this article. Transient model, statistical decision and optic fiber senso r have good foreground.
