摘要
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.
