ABSTRACT

In this paper, X-ray CT scanning was performed on the Berea sandstone core samples to obtain two-dimensional multimedia images. AVIZO software was used to binarize the two-dimensional core images and extract the core pore model. The maximum sphere algorithm was used to characterize the extracted core pores and the pore model, and a 3D pore network model was established. The theoretical method for establishing 3D digital core pore network was described in detail, and the parameter setting method in the algorithm was introduced. The research showed that, AVIZO software could be used to visualize modelling of the 3D digital core pore network, the extracted Berea sandstone pore network had good connectivity, showing obvious pore network size differentiation. The simulation model supported good reduction of the Berea sandstone core, and hydrodynamics related calculation can be carried out in the next step.
