模糊识别方法在储层识别中的应用

The Application of Fuzzy Technique in Reservoir Identification

以储层测井信息所反应的储层地质特性—一种模糊信息为基础，利用模糊识别方法，建立了吐哈油田各种储层测井信息的模糊隶属函数和隶属方程；所得隶属度的大小可以用来判断储层的所属类型。虽然建模过程中需要较多的建模样本，但模糊识别方法是一种多参数方法，它具有思想简单、计算速度快。

Reservoir geological characters as revealed by log data can be considered as a kind of fuzzy information. Based on this information and employing the method of fuzzy identification, fuzzy belonging-functions are derived for the reservoirs of Turpan-Hami basin. The type of reservoirs can thus be determined according to the belonging degree.
