摘要
In Putaohua formation oil set at Pubei oil field, the change of reservoir physical property on plane was controlled by sedimentary microfacies. The effect of common layering and log interpretation model without classifying sedimentary microfacies was not ideal. In view of this characteristics, this paper established interpretation models for porosity and permeability which were constrained by different sedimentary microfacies, which are built on the basis of the correlation of four reservoir parameters. By using the interpretation models, 267 wells in this area are reinterpreted, the result shows that the interpretation models based on different sedimentary microfacies have higher accuracy, and reliable parameters are provided for geologic modeling and remaining oil tapping.
