摘　　要：页岩储层致密,开采难度大,需要依靠水力压裂技术来进行改造增产。因此,准确地表征储层地质参数,明晰页岩储层渗流机理,描述裂缝扩展形态以及复杂裂缝流动机理是高效开发页岩油气的关键。从页岩储层多孔介质表征方法、裂缝扩展模拟方法和页岩储层流动模拟方法展开了讨论。深入分析了常用方法的优势与不足,为进一步研究页岩储层表征的普适性与准确性提供参考。As an important energy source,shale reservoirs are dense and difficult to exploit,it is necessary to stimulate production by hydraulic fracturing.Therefore,it is important to make clear geological parameters and the flow mechanism of complex fractures for highly efficient development of shale reservoirs.Starting from the characterization method of porous media in shale reservoirs,the simulation methods of fracture propagation and of shale reservoir flow,the discussion has been carried out.In-depth analysis of the advantages and disadvantages of existing common methods provides a good reference for further research on the universality and accuracy of shale reservoir characterization.
