Making study on complex resistivity characteristics of reservoir rock must exclude the polarization effect of rock physical measurement systems firstly. Based on measuring device of different metal electrode materials and copper sulfate dough, the complex resistivity experiments with water are completed. In the measuring process, pure resistance and RC parallel circuit are used to calibrate the instrument and measuring apparatus system, which confirms that the performance of copper sulfate dough measuring device is more stable and ensure the accuracy and reliability of the experimental results. On this basis, a complete set of rock complex resistivity measuring and calibrating method are established, optimizing the most stable measuring system and excluding non-rock polarization effect. This study will provide technical support for petrophysical analysis and evaluation of conventional and unconventional oil or gas reservoir.
