| Abstract: | The hydrocarbon charge history of the Silurian bituminous sandstone reservoirs in the Yingmaili area was investigated using an integrated approach by combining detailed petrographic analysis(thin section and SEM),clay mineral XRD characterization,and the modeling of authigenic clay minerals and subsequent K-Ar dating of authigenic illites.The result was correlated within the basin.The ordered mixed-layer illite/smectite(I/S) is dominant in the clay assemblages of the Silurian bituminous sandstones in the Yi... |
