摘　　要：针对储层非均质性定量评价方法有的过于简单、有的又过于复杂、系统性不强等问题,根据集对分析原理和灰色关联度分析,建立了灰色集对分析模型,通过模型计算出联系度和权重,并将该分析模型运用到XC气田须二气藏层内非均质性定量评价中,同时就应用情况进行了评价。Some methods to evaluate quantitatively reservoir heterogeneity are too simple, some are too complicated, and others are poorly systematical. So, based on set pair analysis and grey correlation analysis, a new method, also a model of grey set pair analysis, is established by both correlation degree and weight calculated from the model. This model was applied to Xujiahe 2 gas reservoir, XC gasfield. Results show that grey set pair analysis is effective and is worth popularizing in quantitative evaluation of reservoir heterogeneity.
