对北海白垩样品薄片的扫描电镜图像进行数字化,并用多重分形统计方法进行分析,结果表明这种分析方法可用于区分不同地质特征的白垩地层,尤其是孔隙空间的多重分形谱图的形状与由岩芯测出的渗透率值存在对应关系。
Scanning electron microscope images of the North China chalk samples were digitized and analyzed by multifractal statistics. The results show that this method can be used to distinguish the different geological features of the chalk formation, especially the multifractal spectrum of the pore space, Core permeability values measured there is a correspondence.
