摘要
在我国，作者首次将因子克立格法用于探讨油气藏储层参数的分布规律。通过因子克立格分析，可以将区域化变量分解成不同的空间正文分量，不同的空间分量与空间不同的地质尺度或者说“频率”相对应，往往能找到与不同“频率”相对应的地质作用，进而得出不同地质作用下空间分量的变化规律。这对于探讨地质成因，圈定地质异常有着重要的意义。以河南南阳双河油田核桃园组当中的某一砂岩储层为实例，通过研究，作出了在湖浪作用、河流作用下其渗透率的平面分布规律，并对二维规则网格结点处的渗透率值进行了克立格估计，绘出了等值线图。
The distributive law of reserve parameters of oil-gas reservoir is discussed by first using factoriai Kriging method in China. Factorial Kriging analysis is able to resolve regional variable into different space orthogonal components. If different space components are corresponding to space different geologic dimension, the geologic effects corresponding to different 'frequency' can sometimes be found out to obtain the space component variation law under different geologic effects,which is of significance for discussing geologic origin and delineating geologic abnormality. The permeability plane distributive law under lake-wave effect and fluviation is studied. The permeability value at the nodal point of two-dimensional regular grid is estimated by using Kriging method and the isoline diagram is drawn out.
