摘　　要：通过实验研究和实际资料统计指出,塔里木盆地的砂岩储层在岩心描述中有层状黄铁矿分布或者黄铁矿等导电矿物含量高的井段,其对应的感应测井曲线没有明显反应,说明在一般情况下,砂岩储层中所含导电矿物对储层电阻率没有明显的影响,与理论分析结论一致。Theoretically, the influence of conductive minerals, which are dispersed or thin bedded on the reservoir resistivity, is limited. The results of experimental results and the analysis of really measured data show that there is not apparent correlation between the reservoir resistivity and the content of conductive minerals. In the Tarim basin, the bedded pyrite is found in some intervals of sandstone reservoir in the core descriptions, but the responds of induction curves in the intervals are unconspicuous.
