The linear relation assumes between the mean characteristic parameter , sorting coefficient , variation coefficient of pore structure by rectangular method and the fractal dimension by integrated linear regression , indicating that the fractal dimensions can be used to quantitatively describe the heterogeneity of reservoirs 用由矩法計算所得孔隙結構特征參數均值、分選系數及變異系數與用整體線形回歸所得分形維數的線性關系說明,用分形維數來定量描述儲集層非均質性是可行的。
