Vertical Distribution Heterogeneity of Pore Structure Collected from Deep, Thick Coal Seams
Abstract
Deep coalbed methane (CBM) development in the Eastern Ordos Basin indicates that strong vertical heterogeneity within the Benxi Formation No. 8 thick coal seam can severely constrain well productivity. Here, twelve coal samples from two typical wells (W1: upper coal seams; W2: lower coal seams) were analyzed to quantify vertical variability in pore structure and its controls. Proximate and maceral analyses were combined with low-temperature N2 adsorption (2–100 nm) and CO2 adsorption (
