摘要: 通过在陕南平利某工区ZK301孔及东、南、西、北4个方向分别布极,极距约100m,进行激电测井工作所取得的井中物探测井曲线图,结合工区的岩(矿)石电性参数特征进行分析,得出在该井深112～137m及202～215m两阶段均为弱矿化带,主要由黄铁矿化引起,而在井深225～245m及320～330m两阶段均为强矿化带,主要由闪锌矿化引起。由于钻孔的原因未做其他极距的激电测井工作。并对激电测井工作中应注意事项进行了简单的描述。

Abstract: In borehole ZK301 of a certain working area in Pingli of south Shaanxi,electrodes with a distance of approximately 100 m between every electrodes are arranged.On this basis,we perform the electrical logging and obtain some logging curves.Based on these curves in combination with the electrical parameters,we obtain that the two stages,at adepth of 112-137 m and 202-215 m,are the weakly mineralized zone,mainly caused by pyrite mineralization.However,at adepth of 225-245 m and 320-330 m,it becomes a strongly mineralized zone,mainly caused by the sphalerite.Because of the borehole,no other electrical logtest with different electrode distance has been performed.
