浅谈煤层气气质分析测试技术

摘要

简要分析了我国煤层气气质分析方法现状，通过分析比较目前我国采用的煤层气气质分析方法，结合现场试验，研究了这些方法对煤层气的适应性。结果显示，大部分现有方法对煤层气适应性较好，部分方法需要改进以便更好地适应煤层气气质分析。在此基础上，提出了煤层气分析方法及其标准化建议。%Coalbed methane (CBM ) composition analysis in China is adopting the natural gas sampling and analysis standards at present .In this paper ,the applicability of these standards for CBM was studied by theoretical evaluation and experimental verification .The results show that most of the existing methods are suitable for CBM ,some methods still need to be improved for CBM quality analysis .Based on these studies ,the proposals for improvement of CBM analysis methods and standardization are put forw ard .
