More Information
Summary:The invention discloses a sandstone compaction effect numerical simulation method, and belongs to the technical field of oil and gas reservoir geology. The method includes: reproducing burial history and thermal history of sandstone at a target horizon based on data such as a top surface structure map, stratum thickness, stratum age, denudation thickness and lithologic ratio of all stratums to serve as a compaction effect numerical model; based on sedimentary microfacies plane distribution and single well lithofacies distribution, adopting a deterministic modeling method and a random modeling method to compile a 3D lithofacies model, and taking the 3D lithofacies model as an input parameter of a compaction effect numerical model; evaluating an intergranular volume-depth relation curve and the content of the pressure-soluble quartz cement by adopting quantitative statistical data of a casting body slice and a cathode luminescence slice as numerical simulation parameters of a mechanical compaction effect and a
