论文摘要
我们报告了一个包含岩石塞的全尺度的3D图像的数据集,该数据集通过岩石物理实验室表征数据增加,用于在数字岩石和毛细管网络分析中应用。具体而言,我们已经获得了18个圆柱形砂岩和碳酸盐岩岩样品的显微镜分辨层析成像数据集,其长度分别为25.4毫米,直径为9.5 mm。根据微型摄影数据,我们为每个成像的岩石样品计算了孔隙率值。为了使用互补实验室方法验证计算的孔隙率值,我们使用标准的岩石物理特性技术测量了每个岩石样品的孔隙率。总体而言,基于断层扫描的孔隙率值与从实验室获得的测量结果一致,范围为8%至30%。此外,我们为每个岩石样品提供了实验性渗透率,值范围从0.4 MD到5D以上。该数据集对于建立,基准测试和参考孔隙尺度的储层岩石岩石岩石的关系和渗透率之间的关系至关重要。
We report a dataset containing full-scale, 3D images of rock plugs augmented by petrophysical lab characterization data for application in digital rock and capillary network analysis. Specifically, we have acquired microscopically resolved tomography datasets of 18 cylindrical sandstone and carbonate rock samples having lengths of 25.4 mm and diameters of 9.5 mm, respectively. Based on the micro-tomography data, we have computed porosity-values for each imaged rock sample. For validating the computed porosity values with a complementary lab method, we have measured porosity for each rock sample by using standard petrophysical characterization techniques. Overall, the tomography-based porosity values agree with the measurement results obtained from the lab, with values ranging from 8% to 30%. In addition, we provide for each rock sample the experimental permeabilities, with values ranging from 0.4 mD to above 5D. This dataset will be essential for establishing, benchmarking, and referencing the relation between porosity and permeability of reservoir rock at pore scale.
