WebApr 14, 2024 · Cheng et al. obtained the internal structure of the mixture by CT tomography, and produced continuous 2D slice images by scanning, and finally aggregated the images into a 3D model. Then, Gao et al. [ 16 ] obtained the 3D angle ( 3DA ) of coarse aggregate to characterize its angularity with the help of CT technology. WebThis addresses the issue of ‘CT takes too long’ and ‘CT costs too much’, while also ensuring useful and reproducible results, not simply ‘fancy’ results. The cube porosity analysis (scan plus analysis, entire job) takes a maximum of four hours, with typical service providers charging $150 per hour, to give an idea of an approximate ...

WebApr 3, 2024 · In general, CT scanning relies on X-ray absorption to produce a 3D computed image of the material. In Earth Sciences, $$\upmu \hbox {CT}$$ scans are used to characterize porosity and pore size, shape and topology of rock samples. For sufficiently large pore systems, the resulting segmented images may be used for quantitative … WebJan 1, 2014 · Du Plessis et al.

WebFeb 5, 2024 · According to the obtained data, the calculated porosity, averaged over all selected sections of each CT scan direction, fluctuates in a small range from 1.71% to 2.28% and averages 1.96% for the sample. However, the large values of the standard deviation and the coefficients of variation (58, 54 and 99%, respectively) stand out. WebBased on nano-CT imaging, Wu et al. (2015) analyzed the characteristics of the Ordos Basin lacustrine shale porosity evolution at different temperatures (350 °C, 450 °C, and 550 °C); when the pyrolysis temperature was 350 °C, organic matter was in the late stage of oil generation window and cracked into a mass of hydrocarbon.
