改进的层次分析法在碎屑岩储层评价中的运用

Application of Improved Analytical Hierarchy Process in Clastic Reservior Evaluation

介绍改进的层次分析法基本原理,优选孔隙度、渗透率、泥质含量等评价指标,对研究区目的层储层物性参数进行定量评价,最后确定各因素的权重系数,并依据综合评价因子对太原组、山西组、下石盒子组、上石盒子组储层进行分类。实践应用结果表明,该分类结果与油田实际勘探开发效果一致。

This paper introduces IAHP, and optimizes the porosity, permeability, clay content, and other evalua-tion index, and conducts the quantitative evaluation on target stratum and reservoir physical property parameters. Fi-nally the weighting coefficient which represents the relative materiality of different factors is confirmed. Combinedwith the comprehensive evaluation factors, it is divided into four categories between Taiyuan, Shanxi, Xiashiheziand Shangshihezi group reservoirs. And this classification results have been proved to be consistent with oilfield ex-ploration and development results through practical application.
