摘要
本文仅利用视电阻率和自然电位两种测井曲线的形态特征研究如何定量判别鄂尔多斯盆地东北部沉积相问题。文中提出“测井沉积相”概念,并构造出4个测井曲线形态特征的定量指标,作为判别变量,建立逻辑判别函数模型。经实例验算,判别效果良好。
This paper studies how to discriminate quantitatively the sedimentary fades in the northeastern part of the Ordos Basin using only the shape characteristics information of their apparent resistivity log and spontaneous potential log . In this paper , the author first suggests the concept of 'log sedimentary fades '. Four quantitative indicators of shape characteristics of log curves have been constructed as the discriminative variables to built the logistic discriminative function model . After the test of practical examples , it is shown that the effect of discrimination is good .
