明晰纳微空间受限流体流动机理、计算渗透率等参数对提高页岩油采收率至关重要.评述近年来页岩油微观流动机理和数值方法,讨论了固液分子间相互作用力导致壁面滑移和流体黏度/密度非均质性对页岩油流动过程的影响,总结了表征单纳米孔隙流体流动的4种理论模型(分区模型、有效黏度模型、表观黏度模型和表观滑移长度模型),以及直接模拟方法(分子动力学模拟方法和孔隙尺度格子Boltzmann 模拟方法)和间接模拟方法(孔隙网络模型和耦合直接-间接模拟方法)在研究流体在纳微多孔介质流动行为中的应用,探讨了各模拟方法的优缺点,并提出今后的研究方向.
Clarifying the mechanisms of confined fluid flow in nanoscale space and calculating the permeability and other microscopic parameters are crucial to enhance the recovery of shale oil, which have attracted great attention in recent years. We review the micro flow mechanisms and numerical methods of shale oil, and discuss the effects of the solid-liquid molecular interaction force which leads to boundary slip and viscosity/density heterogeneity on the shale oil flow behaviors. Firstly, we introduce the four analytical models of confined fluid flow in nanopores which are the region-separation model, the effective viscosity model, the apparent viscosity model and the apparent slip length model. Then, we summarize the simulation methods and the applications in the study of fluid flow in nanoporous media Among them, the direct simulation methods are the molecular dynamics simulation (MDS) method and the pore-scale lattice Boltzmann simulation method (LBM), and the indirect simulation methods are the pore network model (PNM) and the coupled direct-indirect simulation method . We discuss the advantages and disadvantages of each simulation method. Finally, on the basis of summarizing the advantages and disadvantages of research results, the future research directions are put forward.
