多孔介质中的不混相驱替对于许多自然过程和工业应用具有重要意义。尽管在这一领域已经做了广泛的工作，但由于难以覆盖大量的影响因素，仍然存在一些局限性。在本文中，我们提出了一项涉及毛细管力、粘性力、润湿特性和孔隙几何形状耦合影响的系统研究。通过高分辨率的微流控实验，清晰地捕获并定量表征了残余流体分布和动态侵入过程。随着毛细管数 Ca 的增加，发现了排水的异常行为。在不利的粘度比 M 的渗吸情况下，发现了异常的留空行为，这表明在中等 Ca 处侵入的许多带状区域在高 Ca 处变得难以进入。具有大典型孔喉比的孔隙几何形状似乎增强了留空行为。在动态侵入过程中，以侵入饱和度增加速率波动的形式捕获了间歇性行为。随着时间的推移，间歇性动态在不利的MA排水中最为明显。高孔隙率的孔隙几何形状可以抑制间歇性行为。我们的实验结果勾勒出不同条件下多孔介质中不混相位移的完整视图，并提供了一个完整的数据集，可用于测试快速发展的孔隙尺度模型。
Immiscible displacements in porous media are fundamentally significant for many natural processes and industrial applications.Although extensive work has been done in this field, some limitations still exist due to the difficulty to cover the large number of influencing factors.In this paper, we present a systematic study involving the coupled influence of capillary forces, viscous forces, wetting properties and pore geometries.By microfluidic experiments with high resolutions, both residual fluid distributions and dynamical invasion processes were clearly captured and quantitatively characterized.A void-filling behavior was identified for drainage as the capillary number Ca increased.An anomalous void-leaving behavior was found for the case of imbibition with an unfavorable viscosity ratio M, representing many ribbon-like regions invaded at intermediate Ca turned to be not accessible at high Ca.A pore geometry with a large typical pore-throat ratio seemed to enhance the void-leaving behavior.During the dynamical invasion processes, an intermittency behavior was captured in the form of a fluctuation of the increasing rate of the invading saturation with time.The intermittency dynamics were most evident for drainage with an unfavorable M.A pore geometry with high porosity acted to suppress the intermittency behaviors.Our experimental results sketched out a full view of immiscible displacements in porous media under different conditions, and provided a complete dataset which could be used to test the rapid developing pore-scale models.
