在断层几何中注入米级实验室CO $_2$的物理变化
Physical variability in meter-scale laboratory CO$_2$ injections in faulted geometries
摘要：
碳捕获和封存（CCS）是应对气候变化向净零过渡的重要桥梁技术。FluidFlower概念已被开发用于在实验室环境中可视化和研究沉积系统中的CO $_2$流动和储存机制。研究了两种地质几何条件下的米级多相流，包括有涂抹和无涂抹的正断层。详细介绍了为数值模拟提供关键输入参数的实验协议，包括对FluidFlower基准研究的操作参数的评估。两种不同几何形状的CO $_2$迁移模式的变异性被量化，在16次重复的实验室运行之间以及在历史匹配的模型和CO $_2$注入实验之间。然后在不同的地质背景下评估历史匹配模型的预测能力。
英文摘要：
Carbon, capture, and storage (CCS) is an important bridging technology to combat climate change in the transition towards net-zero. The FluidFlower concept has been developed to visualize and study CO$_2$ flow and storage mechanisms in sedimentary systems in a laboratory setting. Meter-scale multiphase flow in two geological geometries, including normal faults with and without smearing, is studied. The experimental protocols developed to provide key input parameters for numerical simulations are detailed, including an evaluation of operational parameters for the FluidFlower benchmark study. Variability in CO$_2$ migration patterns for two different geometries is quantified, both between 16 repeated laboratory runs and between history-matched models and a CO$_2$ injection experiment. The predicative capability of a history-matched model is then evaluated in a different geological setting.
