摘　　要：阐述了乙烷分析的气相色谱分离原理,应用基于气相色谱技术的检测设备和技术方法,解决了长期以来地下沼气对天然气管网泄漏判断的干扰问题,避免了无效开挖,节省了开挖费用。通过实际的数据分析,总结出目前北京市的天然气疑似漏点约有40%是地下沼气干扰所致。The separation principle of ethane by gas chromatography is expounded. By using the detection equipment and technical methods based on gas chromatography, the long-term interference of marsh gas with leakage judgment of natural gas network is solved, the invalid excavation is avoided, and the excavation cost is saved. Through the actual data analysis, it is summarized that about 40% of suspicious points of natural gas leakage in Beijing arise from interference of underground marsh gas.
