埋地长输管线流体泄漏的检测与定位

摘要

埋地长输管线是炼化企业原料和产品的必不可少的途径，其沿途涉及范围广，周边环境复杂，泄漏具有隐蔽性和流体介质的危险性。本文对目前流体泄漏检测技术进行了分析，介绍泄漏检测和定位方法的现状，对上述方法的优缺点进行了评述，并对泄漏检测和定位方法的发展方向提出了个人的看法。%The domestic and foreign liquid leakage detection and location techniques were introduced systematically in recent decades. The methods based on hardware and software were mainly discussed, and the advantages and disadvan- tages of the two methods were summarized. Meanwhile, some problems existed in the current methods was presented and the future development directions were pointed out.
