Pore fractal characteristics
WebMar 2, 2024 · The contributions of key pore geometry parameters, including the maximum pore diameter, minimum pore diameter, porosity, and fractal dimensions, to the initial permeability were investigated. A numerical analysis showed that the influence of fractal dimension on the permeability is finally reflected in the influence of pore structure … WebAug 30, 2024 · When quantifying the complexity of shale pores, the fractal dimension is between 2 and 3. The larger the fractal dimension is, the more complex the shale pore structure. The object does not have fractal characteristics if the fractal dimension is less than 2 or greater than 3 (Tang et al., 2024). Results Pore types and characteristics of shale
