多层砂岩油藏层内纵向非均质性表征方法探索
摘要
Abstract
A new method on reservoir heterogeneity characterization in reservoir numerical modeling is presented based on end point scaling of pseudo-relative permeability. The relative permeabilities of each point of well log around accuracy rating are first calculated from the relative permeability, which arises from core flooding tests. Thus the pseudo relative permeability of a substratum consisting of many well log points around accuracy rating is obtained. The function relation between pseudo relative permeability of a substratum and relative permeability from labs is studied, which stimulated the presentation of relative permeabilities of all cells among wells in reservoir numerical modeling. The amount of relative permeability of all cells is determined from reservoir numerical simulator. It has been proved that flow characteristic of oil-water two phases in layered sandstone reservoir could be modeling more accurately based on the above method.关键词
