Research On the Fractal Dimensions of the Organic-Rich Shale Pores Via Different Models

Abstract Fractal dimension can be used to the pore surface characterize. For structures in different sizes, calculation models of fractal theory should distinguished due principles gas adsorption experiments. To further study adaptability model for experimental data, author collected shale samples Longmaxi formation from Well JY1, then CO 2 and N provided PSD curves. In addition, dimensions micropore mesopore were calculated by Jaroniec Frenkel–Halsey–Hill (FHH) respectively. The research shows that may suitable calculate data could characterize micropore, while FHH high relative pressure region. It suggests have evaluation structure pores consider both them.
