Estaillades Carbonate #2

Estaillades carbonate is a mono-mineralic, calcitic rock, which contains two types of pores: intergranular macropores and intra-granular micropores. An Estaillades sample with a diameter of 7mm was scanned with UGCT’s HECTOR micro-CT scanner (developed in collaboration with XRE, www.xre.be). In this micro-CT scan, (most of) the intergranular macropores are resolved, while the micropores are not. A three-phase segmentation consisting of pore voxels, voxels with unresolved porosity, and solid voxels is provided. This image was used to extract a multi-scale pore network model from (Bultreys et al. 2015).

埃斯塔耶德碳酸盐岩（Estaillades carbonate）属于单矿物方解石质岩石，内部存在两类孔隙：粒间大孔隙（intergranular macropores）与粒内微孔（intra-granular micropores）。本次研究采用与XRE合作开发的UGCT HECTOR微CT扫描仪（www.xre.be），对一枚直径7mm的埃斯塔耶德碳酸盐岩样品开展扫描成像。在此次微CT扫描中，（绝大多数）粒间大孔隙可被分辨，而粒内微孔则无法被识别。本数据集附带三相分割结果，包含孔隙体素、未分辨孔隙体素与固体体素。该成像数据被用于提取多尺度孔隙网络模型，相关研究成果见于Bultreys等人2015年的文献。
