| 摘要 |
The invention is a method for simulating sandstone deposition. The sandstone is simulated by estimating the grain size distribution and mineral compositi on of grains (1) in the sandstone, simulating sedimentation (2) of grains from the grain size distribution and mineral composition of the grains, simulatin g compaction (3) of the grains, and simulating cementation (4) of the grains. Properties of the sandstone such as porosity and permeability may be estimat ed from the simulated sandstone. The method permits multiple mineralogies to be simulated during the burial history of sedimentation, compaction and cementation.
