Abstract

Summary

The effects of compaction and cementation on rock permeability are studied by simulating the deposition and diagenetic processes of spherical grains with uniform size. Compaction and cementation are essential parts of the formation of consolidated rock. The simulation of the cementation process uses the morphology algorithm, which ignores many complications and therefore may not represent the real process of rock formation. The single phase fluid flow through the modeled rock is simulated by solving the Navier-Stokes equations. The absolute permeability of the sample is obtained by integrating the flow velocity at the outlet or inlet boundary and combining with Darcy’s law. The simulation shows that compaction and cementation reduce the connectivity and permeability of the deposition model. The results described here are only a preliminary quantitative analysis of the relationship between permeability and diagenetic process, and will be analysed and interpreted in combination with the experimental results in the future.
