Abstract: Transport characteristics in porous media play a significant role in fields, such as oil and gas reservoir engineering, hydraulic engineering, mineral engineering and geology. In this study, based on the fractal theory of porous media, a fractal model for the permeability through micro/nano dual-porosity media considering the coupling effect of the EDL and slip is derived. This study discusses the effects of the original slip length, molar concentration, dip angle, maximum aperture, fractal dimension and maximum size ratio on the dimensionless permeability. The results show that the dimensionless permeability increases with the increases of the original slip length, dip angle, fracture tortuosity fractal dimension, and maximum size ratio; on the contrary, the dimensionless permeability decreases when the molar concentration, maximum aperture, fracture aperture fractal dimension and capillary tortuosity fractal dimension increase. Moreover, the fractal model predictions are in good agreement with experimental data. The proposed model may be able to provide guidance for the analysis of transport properties in micro/nano dual-porosity media.
