摘　　要：储层的非均质性决定了油层的产能,注水的效果和石油的最终采收率。非均质性评价参数的选取以及综合各类地质信息的能力,将直接影响到评价结果的准确性。GIS的储层非均质性灰色综合评价,就是利用地理信息系统管理和分析储层非均质性评价参数,将灰色评价方法与GIS(Geographical Information System)空间分析功能集成,对储层的非均质性进行研究,最后结合已有的地质信息,分析储层的平面非均质性特征。利用该方法可实现储层非均质性研究的一体化评价。Reservoir heterogeneity heavily impacts the producing abilities,effectiveness of water injection and ultimate recovery.Evaluation parameters of reservoir heterogeneity and synthesized ability of all kinds of geology information impact veracity of the appraising results.GIS-based Grey Comprehensive Evaluation on oil-gas reservoir heterogeneity is to evaluate,manage and is and analyze data by GIS techniques.In the paper,Oil-gas reservoir heterogeneity is identified by means of integrating grey comprehensive evaluation method with GIS.Then,combined with geological data,characters of reservoir heterogeneity distribution is analyzed and integrated evaluation of reservoir heterogeneity is realized using the method.
