摘要
在考虑有效厚度、砂体发育特征、油水同层发育状况及储层物性参数等评价指标的基础上,采取层次分析方法确定出评价指标的权重,利用模糊物元评价方法计算了各个区块的综合评价指数。根据综合评价指数的大小,利用累计概率曲线的分类功能将S油田40个区块划分为3种类型:一类区块河道砂发育,油层厚度大,储层物性好;二、三类区块发育薄层席状砂,储层物性差。
On the bases of considering the evaluation indexes such as net pay thickness, developed sandbody char- acteristics, developed conditions of the oil-water costratotype layer, physical parameters of the reservoir and so on, the evaluation indexes are weighted by means of analytic hierarchy process, the comprehensive evaluation index of each block is calculated with the help of fuzzy matter-element evaluating method, and moreover three types of forty blocks in Oilfield S are classified by the dividing function of cumulative probability curves. In detail, Type One is characterized by well-developed channel sandbody, bigger oil reservoir thickness and pretty better physical proper- ties ; Type Two and Three are featured by well-developed thin sand sheet and worse physical properties of the reser- voirs.
