Abstract: | The distribution of sedimentary microfacies in the eighth member of the Shihezi formation (the H8 member) in the Sul4 3D seismic test area was investigated. A Support Vector Machine (SVM) model was introduced for the first time as a way of predicting sandstone thickness in the study area. The model was constructed by analysis and optimization of measured seismic attributes. The distribution of the sedimentary microfacies in the study area was determined from predicted sandstone thickness and an analysis of sedimentary characteristics of the area. The results indicate that sandstone thickness predictions in the study area using an SVM method are good. The distribution of the sedimentary microfacies in the study area has been depicted at a fine scale. |
