2019年5月10日上午，勞倫斯伯克利國家實驗室(Lawrence Berkeley National Laboratory，LBNL)常春博士應邀來訪并作題為“Two-Phase Displacement and Interfacial Interactions: A Case Study on Geological CO2 Sequestration”的學術報告。本次報告由我院樊靜麗副教授主持，我校部分師生總計20餘人參與此次報告。
今天的報告中，常春博士主要分享了在勞倫斯伯克利國家實驗室攻讀期間主要研究成果，對界面不穩定性和溶解性以及他們對二氧化碳存儲效率的影響做了深入分析。通過熒光示蹤染料和顯微鏡的2D微模型實驗，對CO2飽和度和溶解性進行跟蹤和記錄，同時對理論結果和實驗結果的差距做了詳細剖析，強調了不同地質條件下CO2流動的複雜性，對CCS現場部署具有重要意義。報告的最後，在場部分教師和學生與常春博士展開了深入讨論和交流。
常春博士介紹：
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.
