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.
