摘　　要：进入21世纪后,我国的天然气消耗量飞速上升,目前国内输气管道总长度已经达到2.4万公里,预计2010年底将达到3.6万公里。如此绵长的输气管道,随着管道设施的老化、地质结构的变化、地质灾害的发生,天然气的泄漏在所难免。通常天然气管道的泄漏量一般大约要占输气总量的10%。天然气管道泄漏对经济发展、大气环境和社会安全带来了负面影响,因此必须积极开展各种天然气管道泄漏监测技术的研究。本文首先介绍了国内外基于机载平台的天然气管道泄漏监测技术的研究现状,然后阐述了两种主要机载天然气监测技术的工作原理,在分析比较两种技术优缺点的基础上,提出了适合我国国情的机载天然气管道泄漏监测的技术方案,并报道了与此方案相关的基础性研究内容。Since entering the 21st century, the consumption of natural gas has been increased at a high speed in China. At present, the total length of natural gas transport pipelines in our country is 24,000 kilometers and is expected to reach 36,000 kilometers by the end of 2010. For such a long natural gas transport pipeline, gas leakage is unavoidable because of pipeline aging, lithosphere shift and geographic disaster. Usually, the leakage of natural gas transport pipelines account for 10% of the total amount of transported gas. Therefore, the research on various techniques for inspecting the leakage of natural gas transport pipelines should be carried out actively. In this paper, the current research status of airborne natural gas transport pipeline inspection techniques at home and abroad is presented and then the operation principles of two main airborne natural gas transport pipeline inspection techniques are discussed. After the advantages and disadvantages of those two inspection techniques are analyzed, an airborne natural gas transport pipeline inspection technique which suits the specific conditions of our country is proposed and some fundamental research content about this technique is reported.
