利用分形插值曲面研究渗透率的分布特征

RESEARCH ON DISTRIBUTION OF PERMEABILITY BY FRACTAL INTERPOLATION SURFACE

根据分形理论，建立了分形模型，利用分形插值曲面公式形成了某地区的渗透率横向分布曲面，这种渗透率的横向分形分布图直观地显示了地层的渗透特性，为进一步研究该地区孔渗特性，进行沉积相、测井相的研究以及油藏描述提供了有力的证据。

Basing on the fractal theory and its surface interpolation formula,a horizontal subtle distribution surface of permeability can be derived.Comparing with the Krining interpolation method, this surface can display the subtle characteristics of the reservoir permeability.Some reservoir permeability data are used to interpolate by the two methods.The formula can also be used to porosity study.
