摘要: 岩心分析和测井分析表明,沉积岩的物性分布常常具有分形特征;文中用改进实验变差函数分析某油田X探区测井和取心的孔渗数据,得到在某些井中孔渗参数具有分形特征,并采用fGn分形插值技术,得到井间参数的空间分布。

Abstract: Core analysis and logging interpretation show that the property destribution of sdimentary rocks usually is of fractal characteristic. Improved experimental variograms are used in the paper to analyze the porosity and permeability parameters of logging and coring in a certain oilfield. It is observed that in some wells, the parameters are characterized by the fractal, and the fGn frsctal interpolation technologq is utilised to obtain the inter-wells paremeter distribution.
