2019年5月10日上午，劳伦斯伯克利国家实验室(Lawrence Berkeley National Laboratory，LBNL)常春博士应邀来访并作题为“Two-Phase Displacement and Interfacial Interactions: A Case Study on Geological CO2 Sequestration”的学术报告。本次报告由我院樊静丽副教授主持，我校部分师生总计20余人参与此次报告。
今天的报告中，常春博士主要分享了在劳伦斯伯克利国家实验室攻读期间主要研究成果，对界面不稳定性和溶解性以及他们对二氧化碳存储效率的影响做了深入分析。通过荧光示踪染料和显微镜的2D微模型实验，对CO2饱和度和溶解性进行跟踪和记录，同时对理论结果和实验结果的差距做了详细剖析，强调了不同地质条件下CO2流动的复杂性，对CCS现场部署具有重要意义。报告的最后，在场部分教师和学生与常春博士展开了深入讨论和交流。
常春博士介绍：
Dr. Chang is a Postdoctoral fellow in the Energy Geosciences Division at the Lawrence Berkeley National Laboratory (LBNL). His primary research interests are experiment studies on reservoir processes and subsurface hydrology in porous and fractured media, including multiphase flow, phase dissolution and mass transfer, interfacial and wetting phenomena, carbon dioxide sequestration, shale gas & oil and geothermal energy production. At LBNL, He works on the pore-scale supercritical CO2-brine displacement, mass transfer and interfacial wetting effect under reservoir high pressure and high temperature conditions through 2D micromodels with fluorescent tracer dye and microscopy. He also works on fracture-matrix multiphase flow and mass transfer at the core scale with frequent CT imaging. His other interests include approaches to quantitatively describe and characterize permafrost core samples using multi-energy CT scanning.
