长输管线泄漏检测与定位方法分析

ANALYSIS ON LEAKAGE DETECTION AND LOCATION TECHNIQUES FOR LONG TRANSMISSION PIPELINE

油气输送管道的泄漏,会造成损失和危害,及时检测出泄漏并确定泄漏点是至关重要的。为此,系统介绍了近几十年来国内外长输管线的泄漏检测及定位技术,并指出了各种方法的优缺点。随着石油、天然气等工业的发展,管道输送在国民经济中的地位越来越重要,研究出一种可靠、经济的检漏定位方法显得异常重要。文章对泄漏检测与定位技术未来可能发展方向也作了系统的阐述。

Leakage of oil/gas transmission pipelines will cause loss and damage. It is very important to detect the leakage and locate the leakage position in time. The domestic and foreign leakage detection and location techniques are introduced systematically for long transmission pipeline in recent decades years. The advantages and disadvantages of every technique are pointed out. With the development of oil and gas industries, the transmission pipelines play more and more important roles in national economy. It is very important to develop a reliable and economic technique for leakage detection and location. Also, the possible developing direction of leakage detection and location techniques is described thoroughly in the article.
