Abstract

Theoretically, the influence of conductive minerals which are dispersed or thin bedded on the reservoir resistivity is limited. The results of experimental studies and  the analysis of actual data show there are not apparent correlations between the reservoir resistivity and the content of conductive minerals. In Tarim Basin, bedded pyrite is found in some intervals of sandstone reservoir according to core descriptions.But the responds of induction curve in the intervals are not apparent.
