黄河口凹陷相渗曲线构建方法及其应用
Construction Method of Relative Permeability Curve of Huanghekou Sag and Its Application
摘要
Abstract
Because of high core experiment cost,core heterogeneity difference and limited core experiment data,it is difficult to obtain and use a wide range of relative permeability data.For this reason,taking Huanghekou Sag as an example,a construction method of relative permeability curve was presented.The relative permeability experiment data are normalized,the features of the normalized data are extracted by introducing the characteristic indexλreflecting reservoir pore structure difference,and the relationship between relative permeability curve and water saturation can be fitted.Introducing the characteristic indexλ is for eliminating the difference in reservoir pore structure and makes the variation laws of different relative permeability curves tend consistent.The result shows that there is a good correlation betweenλ and irreducible water saturation,the relative permeability curve of Huanghekou Sag obtained using the method has high coincidence degree with core experiment data.This method can be used as an effective method to estimate the oil/water relative permeability in the absence of relative permeability data.关键词
