摘　　要：根据物理测井资料中的自然伽玛值去判断钻孔是否有铝土矿,指导地质人员钻孔采样,为地质人员下一步布置钻孔提供可靠的依据。文章主要通过化验结果和物理测井中的自然伽玛值数据的采集、处理等得出物理测井中的自然伽玛值与本溪组铝土矿中Al_2O_3含量的线性方程式。实践证明,通过建立线性回归方程,判断钻孔是否存在铝土矿,方法是可行的,找矿效果良好。Based to geophysical logging information, natural gamma value was obtained for judging whether or not there is bauxite mineralization in drillhole, so to guide geological personnel for sampling and to provide reliable basis for arranging drilling work. By col- lecting and processing of natural gamma data from the laboratory report and physical logging well, then, the linear equation between natural gamma in physical logging well and content of Al2O3 in bauxite orebody in Benxi formation was calculated. The empirical analy- sis indicates that the linear regression equation has good effect.The method of judging whether there is bauxite in drillhole is feasible.
