Abstract

Abstract

The micro-CT has been an increasingly important tool in researching core pore structure. In this study, a domestically self-developed high-resolution micro-CT equipment is used to capture the CT images of a core sample. Based on the results from digital image analysis of pore core CT images, this paper reconstructs a three-dimensional model of core pore. Then fractal dimension of two-dimension image and three-dimension reconstructed model are calculated based on fractal theory. Finally, the fractal characteristics between the two-dimension image and the three-dimension reconstructed model of the sample are verified by fractal model of porous media. Wherein, the mean difference between the two-dimensional fractal dimension and the three-dimensional fractal dimension is 1.000 3, and the maximum deviation is 0.004. The results well satisfy the relations between the two-dimension and the three-dimension fractal dimension of the fractal model of porous media.
