Fractal analysis of rock pore structure: a comparative study of the matlab-based image method and the mercury intrusion method

SUMMARY

    Conventional sandstone reservoirs, tight sandstone extensively develops a micro- and nano-scale pore throat system, which is manifested by the narrow and non-homogeneous pore throat of the system and has important implications for the study of seepage characteristics and recovery effects of tight reservoirs. Quantitative characterisation of pore structure is necessary for hydrocarbon reservoirs, especially tight reservoirs, and previous studies have shown that fractal analysis is one of the effective tools that can help establish an evaluation method for the pore system of reservoir rocks. In this study, the fractal dimension of the samples is obtained . . .
