| 摘 要： | 根据分形几何理论，提出了一个预测孔隙介质渗透率的分形毛管模型。该模型将介质的微观结构参数和宏观性质相联系，其中的参数反映了介质的孔隙特征和结构特征。由粒状灰岩样品数据证明了该岩石的孔隙尺寸分布是一分形结构，并由此获得了岩石孔道的分维。应用该模型预测的渗管透率值与实测结果一致。

| Abstract: | A fractal capillary model for predicting permeability of a porous medium (eg. grainstone) is presented according to the fractal geometry. The macroscopic properties of the rock are associated with its microstructure parameters by the model in which the parameters reflect the pore-size distribution and microstructure characteristics.The data from a grainstone sample. is used to estimate the fractal dimensions of the poresize distribution and pore trace. Compared the permeability value predicted by the model with the measured value, a good agreement can be observed. |
