摘　　要：复杂储层存在测井油水层识别困难问题。根据模糊数学的隶属函数和最大隶属原则,讨论了模糊综合评判方法和应用准则,建立了测井判别油水层的模糊数学模型。用该模型对××油田20口井的测井资料进行了重新处理,解释符合率达到83.1%,与原解释结论相比提高了7%。It is difficult to identify hydrocarbon and water zones using log data in complex reservoir. Discussed are the fuzzy comprehensive evaluation method and its application principle according to membership function and maximum subordination principle in fuzzy mathematics. The fuzzy mathematics model how to identify hydrocarbon and water zones using log data is set up. With this method, log data from 20 wells in ×× oilfield has been reprocessed, the interpretation agreement rate of which is up to 83. 1%, that is, an increment of 7% compared with the original interpretation.
