英文摘要	This paper describes various laboratory studies that have been performed on Liujiagou sandstone samples from the Ordos basin. The sample characterization includes multi-scale X-ray computed tomography (CT) scanning, and thin section petrographic analysis. Core scale and pore scale characterizations of the Liujiagou formation sandstone were obtained. Injection of liquid CO2 into a brine saturated Liujiagou sandstone core was performed until a steady state condition was observed within a CT scanner. The CO2 filled some of the pore space, moving quickly through the laminae and/or bedding planes of core that were open. Pore/grain scale analysis via thin section petrography classified the Liujiagou sandstone as an arkosic arenite with a quartz/feldspar/rock fragment ratio of 51/32/17 and a mean grain size of 0.35 mm. Primary pores are generally clean and account for 1% of the overall porosity, which was measured as 6% within the thin section analyzed. Understanding how these pore and core scale characteristics of Liujiagou sandstone affect fluid migration through this important Chinese resource will be instrumental in the planning and operation of future CCUS projects.
