摘　　要：针对东河塘油田中后期的水淹层判别问题,提出分形与模糊综合判别解释方法。这种方法先对常规测井曲线进行分形分数维分析,找出相关性强的测井曲线,由此根据试油、生产等资料建立模糊评价矩阵和水淹层解释模型。用该方法处理了十多口井的测井资料,与岩心分析资料对比,效果良好,可以满足在该区块的水淹级别定性识别。A method based on fractal and fuzzy synthetic evaluation was presented for identification of water-out zones in the middle or at late periods of Tarim Donghe Oilfield production.The well log curves with strong corrective characteristics were found by analyzing results of fractal dimension method.Then a fuzzy evaluation matrix and a qualitative interpretation model was established for the water-out zones in the oilfield according to well testing and production data.Data from more than 10 wells are processed with this method.Compared with the core-sealed experimental data,the results are very good,and it can meet the needs of qualitative identification of the water-out zones in this oilfield.
