摘要
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 Yingmaili area except in local areas. They are authigenic in origin. The long distance of the Yingmaili area from the hydrocarbon supply center might be one of the main controlling factors for the relatively late accumulation in this area.
