| 摘 要： | 基于分形理论与技术和广义Darcy定律，考虑孔隙毛细管与裂缝间的窜流效应，提出了幂律流体在裂缝－孔隙双重介质中的有效渗透率分形模型.研究结果表明：幂律流体在裂缝－孔隙双重介质中的有效渗透率不仅与幂律流体特性有关，而且还与裂缝－孔隙双重介质微结构参数、沿基质与裂缝压强差之比有关，同时进一步分析了这些参数对幂律流体有效渗透率的影响.

| Abstract: | The fractal model of the effective permeability for the power-law fluid in fracture-matrix dual porosity medium is developed based on the fractal theory and technology and the generalized Darcy's law by considering the transfer of power-law fluids from porous matrix to fracture. The results show that the effective permeability for the power-law fluid in fracture-matrix dual porosity medium is dependent not only on the properties of power-law fluids， but also on the microstructural parameters of fracture-matrix dual porosity medium and the ratio of Δpm/Δpf of the pressure difference along the porous matrix to that along the fracture. Furthermore the impacts of these factors on the effective permeability for the power-law fluid are also analyzed. |
