Bentheimer Sandstone for Analyzing Wetting Phenomena

The micro-CT image data of Bentheimer sandstone used in characterizing its wettability. The primary drainage and imbibition experiments were performed by using air and brine. The images were acquired at irreducible air saturation Sw=94%. This dataset is used to characterize wetting in complex subsurface multiphase systems by using principles of topology and integral geometry.

本数据集为用于表征本特海默砂岩（Bentheimer sandstone）润湿性的显微计算机断层扫描（micro-CT）图像数据。本次实验以空气与地层盐水为介质，开展了初次驱替与自吸实验。图像采集于残余空气饱和度条件下，此时含水饱和度Sw=94%。本数据集依托拓扑学与积分几何学原理，可用于表征复杂地下多相流系统的润湿性特征。
