3-D Porous Media Reconstruction using a 2-D Micro-CT Image and MPS

AbstractMultiple-point geostatistics (MPS) is a new branch of geoscience, allowing extracting the characteristics from training images and copying them to simulated images. To reconstruct 3-D porous media is quite important to the science of mechanisms of fluids flow and industrial fields. However, accurate reconstruction of porous media is not easy using traditional interpolation methods. Therefore, a real 2-D micro-CT image and MPS are used to reconstruct the 3-D structures of porous media. A cross-section of porous media, with the resolution of 10 microns, obtained by micro-CT scanning is used as an original training image. By using MPS and extracted sample points from each former regenerated training image, each newly reconstructed image is taken as a new training image to predict its next layer. Then, the stochastic 3-D images of porous media are generated by stacking all the reconstructed layers successively. The permeability of the target image composed of real sandstone volume data and the reconst...
