Nitrogen and brine injected into Estaillades carbonate - steady-state experiments

This data is micro-CT images of the simultaneous injection of nitrogen and brine into a porous carbonate rock (Estaillades). The images were acquired during steady-state, which was deduced from a plateau in the differential pressure across the sample. The experiments were conducted in the capillary dominated regime (the total flow rate was kept constant, with the fractional flow (fw) changed in sequence 0.85fw, 0.7fw, 0.5fw, 0.25fw, 0.03fw, 0fw). There is the high Ca experiment where the total flow rate was kept constant at 0.8ml/min and a low Ca experiment where the flow rate was kept constant at 0.1ml/min. The data set includes the tomograms and segmented data for a 1000x1000x1000 voxel cube (voxel size = 3.9 microns). This data set is described in detail in the publications: https://doi.org/10.1103/PhysRevE.100.043115 and https://journals.aps.org/pre/abstract/10.1103/PhysRevE.100.043103

本数据集为同时向多孔碳酸盐岩（Estaillades）中注入氮气与盐水的显微CT（micro-CT）图像。该类图像采集于稳态条件，稳态通过样品两端压差的平台期予以判定。实验开展于毛细主导流动区域，该区域内总流速保持恒定，分流率（fw）依次按0.85fw、0.7fw、0.5fw、0.25fw、0.03fw、0fw的序列进行调整。本数据集包含两组对照实验：高钙实验组与低钙实验组，其中高钙组总流速恒定为0.8ml/min，低钙组总流速恒定为0.1ml/min。数据集包含尺寸为1000×1000×1000体素的立方体断层扫描图像与分割数据，体素尺寸为3.9微米。本数据集的详细说明可参阅以下两篇学术文献：https://doi.org/10.1103/PhysRevE.100.043115 与 https://journals.aps.org/pre/abstract/10.1103/PhysRevE.100.043103
