摘要

二氧化碳捕獲與地質封存技術是我國溫室氣體減量關鍵技術之一，藉由封存評估、監測與模擬等核心技術之建立，我們期望協助及加速推動封存前導試驗及後續的大型示範運轉。本研究整合反射震測、大地電磁及微震監測，透過地球物理併合成像技術以及剪力波分離技術，提昇對於封存場址之地下構造形貌掌握程度。為瞭解二氧化碳注儲後的行為，本研究透過數值傳輸模擬技術預測大規模注儲時及注儲結束後二氧化碳團塊的移棲反應。本研究已架構評估、監測技術框架，提供注儲與監測策略擬定之重要依據。

Carbon dioxide capture and geosequestration is one of key greenhouse gas abatement technologies in Taiwan. To assist and accelerate the pilot-scale and large-scale demonstrations, ITRI has establish core techniques for site evaluation, monitoring, and numerical transport simulation for geosequestration in Taiwan. We have developed joint geophysical imaging and shear-wave splitting techniques to integrate seismic reflection, microseismic and magneto-telluric data that can reveal more detailed insights of underground geological structures in potential injection site. Numerical transport simulation technique is also developed to predict the behavior of carbon dioxide plume during and after large-scale injection. By implement these core technologies, we have constructed a framework for site evaluation and monitoring, which will provide a good basis for site planning and monitoring strategy.
