Dynamic reservoir-condition microtomography of reactive transport in complex carbonates: Effect of initial pore structure and initial brine pH in Ketton, Estaillades, and Portland Limestones.

A laboratory µ-CT scanner was used to image the dissolution of Ketton, Estaillades, and Portland limestones in the presence of CO2-acidified brine at reservoir conditions (10 MPa and 50 °C) at two injected acid strengths for a period of 4 h. Each sample was scanned between 6 and 10 times at ~4 µm resolution and multiple effluent samples were extracted. See also paper: H.P. Menke et al.

实验室微计算机断层扫描仪被用于在水库条件（10 MPa和50°C）下，对Ketton、Estaillades和波特兰石灰石在二氧化碳酸化卤水存在下的溶解过程进行成像。实验在两种注入酸强度下进行了4小时。每个样品在约4 µm的分辨率下扫描了6至10次，并提取了多个尾水样品。参见相关论文：H.P. Menke等，《地球化学与宇宙化学学报》第204卷（2017年），第267-285页。https://doi.org/10.1016/j.gca.2017.01.053。
