摘要: 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、模式识别符合率高等特点。

Abstract: Reservoir geological characters as revealed by log data can be considered as a kind of fuzzy informa-tion. 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 de-
termined according to the belonging degree.

Key words: Reservoir, Log information, Viscous crudeoil, Fuzzy identification
