摘要
大量的理论和实验研究证明,油气藏渗流力学中渗透率的分布、孔隙度的分布、裂缝性油气藏中裂缝网络的分布等许多现象都具有标度不变性。对气水两相在裂缝-孔隙模型和平面径向流模型中进行了微观渗流实验,对实验结果进行了黑白二值化处理,得到了其分形维数。在分形理论的基础上,建立了裂缝-孔隙介质中气水两相分形渗流的数学模型及差分模型。
Many theories and experimental researches proved that lots of phenomenones have scale invariance in oil-gas flow mechanics,such as reservoir permeability distribution,porosity distribution,network distribution of the fracture reservoir.Micro-flow experiments were carried out in gas-water fracture-porosity model and planar radial flow model.Black and white binarization processing of experimental results was used to obtain its fractal dimension.Based on fracture theory,we established the math model and difference model on a two(gas-water)phases fractal flow within fracture-porosity medium.
