摘要
分析了影响断层封闭性的7种主要因素,综合考虑这些因素对断层封闭性贡献的大小,采用模糊数学方法对断层封闭性进行定量评价,建立了断层封闭性模糊综合评价数学模型。运用该模型对坨28断块内7条断层在沙二段的封闭程度进行了评价,评价结果与注水开发效果吻合较好,证明该方法可信。
Seven major influence factors on faults sealing property were analyzed. After comprehensively considering the factors and their contribution to the fault sealing property, the fuzzy mathematical method was applied to e-valuate the fault sealing property. The fuzzy mathematical model for comprehensive evaluation on the fault sealing property was made. The sealing degree of seven faults in Es2 of Tuo28 fault block was evaluated using this model. The evaluated results tally better with the water flood development results of this area, which proved method reliable.
