Challenges and Prospects of Digital Core-Reconstruction Research

Figure 7

Particle swarm optimization (a), Fourier transform-based Gaussian field method (b), and simulated annealing method (c) reconstruction results of 3D digital core. Among them, the 3D digital core with the same background color is the skeleton, and the white part is the pores. It can be observed that the reconstruction effect of particle swarm optimization is better than that of the simulated annealing algorithm, and the obtained 3D digital core has better connectivity in the pore space.
