Data for: Fractal characteristics based on different statistical objects of digital rock models

This compression file contains the programs of constructing digital rock models and calculating fractal dimensions.In our work, the process-based modeling technique is utilized to construct models with different pore structure firstly, which includes four kinds: grain-size contrast, grain-size variety, compaction and cementation. Then the fractal dimensions of solid, pore and interface are calculated simultaneously using the box counting method through different statistical objects. At the same time, it includes the further analysis between fractal dimensions and digital rock models.
