| Research Abstract |
In this study, we applied the different specs of X-ray CT scanners to the evaluation of the fluid flow and geometry of pore structures of the rock samples. We are operating industrial use of X-ray CT scanner and micro-focus X-ray scanners, and the synthetic method to evaluate fluid flow and structures from macro scale of several centi meters to micro scale of several micro meters. Especially, we have conducted the flow tests of supercritical/liquid state of CO2 to the water saturated rock samples, and the state of CO2 in the pores was clearly visualized and the replacement ratio, which represents how much pore spaces are replaced by CO2, was successfully evaluated.
