摘要

介绍了灰色系统理论在储层评价中的应用。首先采用谱系聚类分析方法选择相对独立的评价参 数,从10 个参数中选择了6 个参数用于储层综合评价,分别为变异系数、泥质含量、有效厚度、含油饱和 度、孔隙度、渗透率;并用灰色系统理论关联分析法确定了各参数的权系数。在计算储层综合评价指标值 的基础上,采用拐点法确定储层综合评价的分类阈值,进而对葡萄花油田进行了储层综合定量评价,取得 了较好的效果。葡北地区以Ⅰ类、Ⅱ类储层为主,葡南地区以Ⅱ类、Ⅲ类储层为主。

Abstract

The application of grey systemtheory to reservoir evaluation is introduced. The hierarchical-cluster analysis is firstly adopted to select relatively independent evaluation parameters, and six parameters are selected out of ten parameters, including variation coefficient, shale content, effective thickness, oil saturation, porosity and permeability. And then correlation analysis of grey systemtheory is used to determine the weight coefficient of each parameter. Based on calculation of the indexes for comprehensive evaluation of reservoir, inflection-point method is adopted to determine the classifying thresholds for the comprehensive evaluation of reservoir, and then conduct comprehensive quantitative evaluation. Good evaluation effects have been achieved. There are mainly type I and II reservoir in northern Putaohua Oilfield, and type II and III reservoir in southern Putaohua Oilfield.
