摘　　要：在可地浸砂岩型铀矿找矿工作中经常采用视电阻率测井,井径测量,天然伽玛测井曲线定性划分钻孔剖面岩性.但在顶山地区的部分钻孔,采用以上方法划分钻孔剖面岩性不准确,与钻孔岩心地质编录有很大差异,这时引入自然电位测井曲线综合分析可以提高划分岩性的准确性.Apparent resistivity logging, well diameter measurement and natural gamma logging curves are normally used in quantitative lithological division of borehole sections in the course of exploration of in-situ leachable sandstone-type uranium . But inaccuracy occurred by applying these means for part of boreholes in Dinshan area, and the result is quite different from manual recording of cores. The introduction of spontaneous potential logging curves in this case improves a lot the accuracy of litholgical division.
