Pomiary porowatości skał metodą rentgenowskiej mikrotomografii komputerowej (Micro-CT)

Abstract

Roentgen computed microtomography is an imaging technique that generates high resolution 3D images of internal structure, basing on difference in X-rays absorption inside the sample. Micro-CT provides new possibilities to obtain up to few microns resolution images of reservoir rocks in non destructive way. Such images enables to visualize and quantitative analysis of mineral composition and pore structure (volume, shape and pore throat diameter), which can be used to better understanding petrophysical properties such as permeability. This paper shows test of direct, quantitative porosity measurement based on 3D images obtained using Benchtop device and AVIZO software.
