中文摘要：

基于近年来页岩孔隙中流动规律研究的大量文献调研成果，对较为经典的Beskok-Kar-niadakis理论、Javadpour模型、Civan模型和Swaim模型及各种改进模型进行了研究，重点分析了微纳米孔隙中滑脱流态和过渡流态的计算模型、修正公式及分配系数的设计方法。对于跨流态的流量计算，需要厘清各微观作用机理导致的壁面效应，避免流量的重复计算。采用表观渗透率来等效页岩的渗流能力能够综合体现页岩气藏中特有的流动机理，有效修正微纳米孔隙中不同流态的非达西渗流。如何建立既考虑宏观尺度的流动形态，又考虑孔隙微观作用机理的表观渗透率模型，成为页岩微纳米尺度流动理论的研究方向。

英文摘要：

Based on the results of a large amount of literature research on flow patterns in shale pores, the classical models including Beskok-Karniadakis theory, Javadpour model, Civan model and Swaim model and many modified models are investigated to analyze calculation models, modified equations and design methods for distribution factors for slip flow and transition flow in micro-nano pores. The wall effect caused by microcosmic mechanisms should be understood clearly for flow rate calculation of trans-flow regime, so that the overlap of flow rate calculation is avoi- ded. The application of apparent permeability to characterize the equivalent percolation capacity of shale reveals the combined flow mechanisms in shale gas reservoirs and modifies several non-Darey flow regimes in Micro-nano pores. The establishment of apparent permeability models considering both macro flow regimes and microcosmic mechanisms in pores is the future direction in the research on the theory of shale micro-nano flow.
