摘要:
为精确分析天然气管道穿越水体或淤泥表面冒出气泡中气体全部组分及摩尔含量，排除天然气管道泄漏的可能性，对采集气体样品进行气相色谱检测与甲烷碳同位素相对含量检测。结果表明：通过对比穿越水体管道内天然气组分发现，2类气体样品存在很大特征性差异，排除天然气管道泄漏可能性。研究结果可为类似事件处置提供理论依据。
Abstract:
In order to accurately analyze all the components and molar content of the gas in the bubbles from the natural gas pipeline passing through the water body or the silt surface,and to eliminate the possibility of natural gas pipeline leakage,the collected gas samples were detected by the gas chromatography and the relative content of methane carbon isotope.By comparing the components of natural gas in pipelines passing through the water body,it was found that the two types of gas samples had great characteristic difference,which excluded the possibility of natural gas pipeline leakage.The research results provide a theoretical basis for handling the similar incidents.
