| 摘 要： | 目前在区块整体调剖多因素模糊选井综合评判模型中使用常权向量存在一些缺陷 ,为此提出了在模糊评判模型中使用变权向量的方法及变权所遵循的两条公理。该方法可根据评判井的特征自动调整权向量 ,并能克服常权评判中因评判井资料缺乏而带来的评判偏差。现场应用结果表明 ,用该方法选择的整体调剖井比采用常权方法更加合理、可靠 |

| Abstract: | There are some shortcomings in the fuzzy integrative evaluation model with constant weights applied to select the optimum candidate wells for block profile control. A new fuzzy model with variable weights that can avoid the shortcomings is proposed. The method and two theorems for applying the variable weights are presented. The weights can be automatically adjusted in accordance with the evaluated wells. This method can avoid some errors resulted from the constant weights. The result of practical application shows that the candidate wells selected by using variable weights method are more reasonable and reliable than that by the constant weight method. |
| Keywords: | fuzzy evaluation constant weight variable weight profile control candidate well selection |
