       多孔介质中的多相流与油藏岩石中的油气开采，水污染，二氧化碳地质埋存等诸多工程过程息息相关。孔隙尺度模拟作为实验室测试之外的另一种方法，它首先可为链接孔隙尺度属性（比如说孔隙形态和润湿性）、驱替机理与连续尺度多孔介质多相流的有效桥梁；其次它可帮助我们确定毛细管压力和相对渗透率曲线等连续尺度模拟所需的重要流动函数。从文献来看，毛管束模型（BCTM），直接孔隙尺度模拟（DPSM）和孔隙网络模型（PNM）这三种模拟方法似乎是最被广泛接受的研究流体-流体、流体-基质相互作用等孔隙尺度机理的数值方法。在这一综述，我们详细阐述了多孔介质多相流孔隙尺度模拟方法以及它们的优缺点；同时也强调了孔隙尺度模拟所面临的主要挑战，其中包括接触角的表征，孔隙尺度模拟方法的验证以及从孔隙尺度到岩甚至矿场尺度的尺度升级问题。

Abstract：

    Multiphase flow in porous media is relevant to amount of engineering processes, such as hydrocarbon extraction from reservoir rock, water contamination, CO2 geological storage and sequestration. Pore scale modeling, as an alternative approach to lab measurement, firstly serves as an effective bridge to link the pore scale properties (pore geometry and wettability) and displacement mechanisms to continuous scale multiphase flow in porous media; and secondly allows us to determine essential flow functions, such as capillary pressure and relative permeability curves, which are required for continuous scale modeling. In the literature, three methodologies, Bundle of Capillary Tube Modeling (BCTM), Direct Pore Scale Modeling (DPSM) and Pore Network Modeling (PNM), have appeared to be mostly widely adopted in the investigation of the pore-scale mechanics of fluid-fluid and fluid-solid interactions in porous media by numerical simulation. In this review article, a comprehensive review is provided to show their strengths and weaknesses and to highlight challenges that are faced in modelling of multiphase flow, key challenges include: are contact angle characterization, validation and upscale pore scale findings to core, or even field scale.

Keywords: Multiphase flow, pore scale modeling, bundle of capillary tube modeling, direct pore scale modeling, pore network modeling.
