摘　　要：为了更加精准有效地勘查铝土矿,通过对以往煤田测井项目、各岩层地球物理特征的分析研究,提出了应用测井勘查铝土矿的措施。选取自然伽马等在煤田测井项目中反映较好的测井参数,通过在河南省新密、登封、偃龙、荥巩等豫西铝土矿勘探项目进行验证,将解释结果与地质编录进行比对。实践应用表明,利用自然伽马等测井参数判定铝土矿层具有一定的可行性。In order to explore bauxite more accurately and effectively,through the analysis and research of the past coal field logging projects and geophysical characteristics of each rock stratum,the measures of applying logging to explore bauxite were put forward.Natural gamma ray was selected to reflect better logging parameters in coalfield logging projects.The interpretation results were compared with geological cataloguing by validating the exploration projects of Xinmi,Dengfeng,Yanlong and Xinggong bauxite deposits in Western Henan Province.Practical application showed that it was feasible to use log parameters such as natural gamma ray to determine bauxite deposit.
