| 摘 要： | 讨论了用岩心分析孔隙度与密度测井数据建立孔度模型中回归变量的选取问题，并对传统回归中交换回归自变量的方法进行了比较，提出了数据点到回归直线距离的平方和最小的回归方法，该方法具有坐标不变性，最后比较了三种回归结果在计算孔隙度时的优劣。

| Abstract: | Based on porosity from core analysis and densilog,how to select regressionvariable in establishing porosity model is discussed.Through exchange of regressionvariables and comparison made,a regression method is proposed,which demands theleast sum of square distance between data point and regression line.It is a methodwith coordinate consistency.At last,comparison and analysis are made among thethree regression results in porosity calculations. |
