METHOD FOR DETERMINING PERMEABILITY OF ROCK FORMATION USING COMPUTER TOMOGRAPHIC IMAGES THEREOF
摘要
A method for estimating permeability properties of a porous material from a sample thereof includes making a three dimensional tomographic image of the sample of the material. The image is segmented into pixels each representing pore space or rock grains. The image is divided into sub-volumes. A porosity is estimated for each sub-volume. The components of a permeability tensor are determined by conducting simulations. Principal permeability values and directions are then calculated. The permeability properties are stored in a computer or displayed.
