用模糊聚类和逐步判别分析方法识别低电阻率油气层的方法研究

INVESTIGATION INTO THE METHOD OF CONDUCTIVE OIL GAS BED IDENTIFICATION USING FUZZY CLUSTER ANALYSIS AND STEPWISE DISCRIMINANT ANALYSIS METHODS

针对低电阻率油气层成因的多样性、复杂性 ,利用模糊聚类分析技术、逐步判别分析等方法 ,对辽河油田海南构造带 42口井进行低电阻率油气层的识别 ,建立一套识别低电阻率油气层行之有效的测井解释方法。

Aiming at the variety and the complexity of the cause for low resistivity reservoir fuzzy cluster analysis technique and stepwise discriminant analysis methods have been used for 42 wells to identify the conductive oil gas bed in Hainan structure in Liaohe oil field. A set of effective log interpretation method of identification for low resitivity reservior has been built. The real examples show that these techniques are quite useful for finding conductive oil gas reservior in several old wells and new wells.
