Research Initiation: Visualization of Fluid Displacements in Permeable Media Using X-Ray Computed Tomography

这项研究的目的是获得数据，以验证与提高采收率相关的多孔介质中两相流动的数值模拟。利用X射线计算机层析成像技术将绘制多孔介质内流体饱和度的时间和空间变化。同样的技术将被用来获得关于多孔性介质的局部孔隙度(从而渗透率)的信息。混相、不混相和气体置换将被可视化。这项研究可能有助于更有效地从油藏中开采石油。

This research is aimed at obtaining data to validate numerical modeling of two-phase flow in porous media relevant to enhanced oil recovery. The temporal and spatial variations of fluid saturation within a porous medium will be mapped using X-ray computer tomography imaging technology. This same technique will be used to obtain information on the local porosity (and hence permeability) of the porous media. Miscible, immiscible and gas displacements will be visualized. The research may contribute to more efficient recovery of petroleum from reservoirs.
