The Chang 8 oil reservoir set in Jiyuan area is typical tight sandstone reservoir with lowporosity and permeability. Due to the complex pore structure and strong reservoir heterogeneity, it is circumscribed to calculate the porosity by the traditional way. Combined with the geological characteristics ofChang 8 oil reservoir set in Jiyuan area, generalized regression neural network was applied to predict the porosity of tight sandstone reservoir. The result shows that the porosity predicted by the generalized regression neural network method is consistent with the porosity by well core analysis. Therefore, this method is of very good application value on porosity prediction of tight sandstone reservoir in the non-cored area.
