Study on Variation Law of Coalbed Methane Physical Property Parameters with Seam Depth

According to high difficult development caused by high geostress and low permeability features of the coalbed methane in deep seam,the paper analyzed the rock core test data of the coalbed methane well in the south part of Qinshui Basin and the logging,well test,fracturing,production and other actual informations of the coalbed methane well and studied the relationship between the physical property parameters of main reservoir and depth. The...
