基于主成分分析法的N油田M油组储层岩性识别
Lithology identification of M group of N oilfield based on principal component analysis method
摘要
Abstract
This paper is a response to conventional lithology identification method which fails to meet the actual needs of production when it is applied to identify complex lithology of Nanyishan M group and too many types of rocks, and reservoir generally containing calcium carbonate component and mud. The paper proposes the lithology identification method based on principal component analysis. The method begins with classifying the lithology, investigating logging response characteristics of different rock types, and optimizing acoustic time sensitive to the lithology variation, and compensated neutron curve, and proceeds with determining lithology by using principal component analysis, recognizing principal component and producing identification chart. The chart applied to identify lithology of the study area features an i-dentification coincidence rate of up to 87. 5% , and affords a better effect.关键词
