    A Complex Network Approach for Quantitative Characterization and Robustness Analysis of Sandstone Pore Network Structure by Yuhao Hu, Guannan Liu, Feng Gao, Fengtian Yue, Tao Gao

    Published 2021-01-01
    “…Then, in view of the problem, which is difficult to quantify the detailed topological structure of the sandstone pore networks in the previous study, the new complex network theory is used to characterize the pore structure. PageRank algorithm is based on the number of connections between targets as a measure index to rank the targets, so the network degree distribution, average path length, clustering coefficient, and robustness based on PageRank algorithm and permeability-related topological parameters are studied. …”
