| 摘 要： | 煤层含气量及其影响因素是煤层气勘探开发中首先要研究的问题。通过对煤层含气量影响因素评价中灰色关联分析法与相关分析法的论述,并在分析各自优缺点的同时,对比讨论了两种方法在沁水盆地晋城矿区的应用情况。结果表明,在对各因素的评价结果和区分效果上,相关分析法优于灰色关联分析法。

| Abstract: | It is important to study coalbed methane content and its influence factors for coalbed methane explora-tion.It’s essential to research and evaluate the influence factors correctly and reasonably.The paper discussed and analyzed the association analysis of grey incidence and correlation analysis.After the discussion of their disadvan-tages and advantages the paper evaluated the instance of the Qinshui basin.It is found out that the correlation analysis method is more suitable than the association analysis of grey incidence in evaluation of coalbed methane. |

| Keywords: | evaluation of coalbed methane content relevance the association analysis of grey incidence correlation analysis |
