A reconstruction technique for three dimensional porous media using image analysis and fourier transform

This paper reconstructs the three dimensional porous media from the porosity and the autocorrelation function obtained from the 2D thin section of a real porous media using a truncated Gaussian method based on Fourier transforms. The results show that the random field obtained by the Fourier transform satisfies the Gaussian distribution and the statistical properties between the reconstructed porous media and the 2D thin section are approximately identical. It indicates that the proper 3D porous media can be reconstructed using the technique above and the technique establishes the basis for the further study on the complicated heat and mass transfer in the porous media.
