This paper presented a newly developed quantitative simulation for sandstone porosity evolution. The methodology was based on burial history and diagenetic history of strata. The impact of both destructive and constructive diagenesis on porosity was taken into account. The porosity evolution model was characterized by: 1) time as the variable that reflected the dynamic process of porosity evolution; 2) current porosity as boundary constraint conditions whose results were reliable; and 3) full consideration of the impact of compaction, cementation and secondary dissolution. The mode was applied to simulating the porosity evolution of the Member 8 of the Yanchang Formation in the Zhenjing area in the Ordos Basin. The application of this approach indicated that it could be widely used in paleoporosity restoration and porosity evolution simulation.
