The connection between macroscopical and micro-seepage of porous media and the significance of micro-seepage research are discussed. The domestic and international research questions about the microscopic structure of seepage flow and the main research methods are summarized. The research characteristics and research methods of various microscopic physical models and corresponding mathematical models are analyzed. The stochastic simulation method and the global ascending method are compared. The advantages and disadvantages of the two methods are pointed out. Finally, the development trend of micro-seepage in porous media is prospected.
