裂缝网络多孔介质渗流特性研究

Study on the seepage characteristics in fractured network porous media

作为裂缝网络型多孔介质渗流特性研究的基础,本文忽略了母体材料的渗流影响,主要讨论了分形分叉网络模型的渗流特性,其中包括压力、流量、阻力和渗透率等输运参数与裂缝网络结构、孔隙率的关系,给出了显式表达式.并给出了这些输运参数与裂缝网络结构的标度关系.

As the fundamental research of the seepage characteristics of fractured network porous media,the seepage characteristics of the fractal bifurcate network model are discussed but the effects of the seepage of the parent material of the porous media on the seepage characteristics are not considered.The seepage characteristics include the relationships between some transport parameters,such as pressure,flow rate,flow resistance,permeability etc.and the fractured network structure and porosity of the porous media,their explicit expressions are presented.The relationships between the transport parameters and the micro-structural parameters of the fractured networks are also discussed.
