摘要: 针对文南油田W33区块一些注水井的数据,利用灰色系统理论中的灰色评判方法,确定相应的灰类,建立因素集、评语集和权重集,通过已知子系统和未知子系统的关联分析,计算综合关联度。根据该指标可定量预测未知系统的特征,所得结果可为油田决策者采取进一步的措施提供一定的理论根据。Abstract: Grey judgment method in grey system theory is used to determine grey class with water injection wells data in WenNan oilfield W33block. The factor set, comment set and weighting set have been made. The relationship between known sub - system and unknown sub - system is analyzed and comprehensive co - relation degree is calculated, which can be quantitative predict unknown system. The results can be provided to oilfield policymaker for ref-
