Fig. 3

Comprehensive histogram of 8 # coal Q36 well in Benxi Formation of Ordos Basin. It can be found that with the change of depth, the lower layer shows low porosity, high inorganic sulfur, low vitrinite and high ash content, and has strong heterogeneity characteristics; the upper layer shows high porosity, high organic sulfur, high vitrinite and low ash content.
