摘要: X-ray computed tomography (CT) is often utilized to evaluate and characterize structural characteristics within reservoir core material systems. Generally, medical CT scanners have been employed because of their availability ease use. Of interest lately has the acquisition three-dimensional, high resolution descriptions rock pore structures for characterization porous media modeling single multiphase transport processes. The spatial current too coarse level imaging most samples. Recently developed microtomography (CMT) using synchrotron sources analogous conventional scanning provides ability obtain three-dimensional images specimens with a on order micrometers. Application this technique study samples two- description structure mineral distributions. Pore space interconnectivity accurately characterized visualized. Computed data can serve as input into pore-level simulation techniques. A generalized explanation provided, comparison techniques results. microtomographic results several sandstone are presented discussed. Bulk porosity values mineralogical identification were obtained from microtomograms compared gas electron microscope tandem
