Combining with studying results of reservoir microfacies,the method uses well position and microfacies information as a input parameters of neural network to make space prediction of reservoir parameters. Taking Bo 21 fault block oil reservoir, Gudao Oilfield as an example,the paper uses permeability data in separate well position and regional depositional microfacies data to make interpolation prediction of inter well permeability. The results show that the method can not only conveniently use prior regional knowledge and expert experiences for prediction of inter well parameters,but also greatly improve the precision of predicted inter well parameters,which provided a reliable basis for reservoir model building.
