摘要: This paper presents a stochastic analysis of coalbed methane (CBM) resources for coal seam in southeast Qinshui Basin, China. Log and laboratory data are used to predict the thickness, ash content gas content. Using reservoir modelling, distributions karst collapse column (KCC), quality generated. The convergent interpolation sequential Gaussian simulation methods model surface structure seam. structural models determined by thickness. Based on models, KCC converted two facies their obtained using object modelling. density simulated based each simulation. Finally, different realisations study CBM resources. results show that heterogeneities thickness lead significant uncertainty estimating A with lower heterogeneity gives greater resource. KCC, main sources resource estimation. variogram top contribute less
