Abstract: Nadu formation of centre depression in the east of Baise Basin is continental clastic deposit formation.The characteristics of reservoir are complex rock structure with poor physical property,low porosity and permeability,and very strong anisotropy.Therefore,it is difficult to predict the initial production using traditional model.Based on logging data and reservoir property,the Cross-area model using oil instruction OID and pore structure parameter m is used to predict the initial production.Combining factors influencing the porosity,shale content,oil saturation,thickness and permeability,the precision and efficiency are greatly increased through using the method of Cross-area in compacted clastic reservoir in Nadu formation.
