Prediction of higher-permeability region for CBM exploration based on multivariate regression analysis:A case study from Qinshui Basin

The coal reservoir's permeability is one of the most important parameters in controlling CBM exploration.Taken Qinshui Basin as an example and based on its properties,the coal reservoir's permeability is predicted by multivariate regression analysis.The regression equation has a high fitting degree.The higher-permeability region for CBM exploration are Panzhuang-Yangcheng,Yangquan-Shouyang and Taiyuan Xishan coalfield in Qinshui Basin.
