The utility model belongs to an array-type electrode system of an induced polarization potential logging instrument in the field of matching measuring instruments of logging instruments. The array-type electrode system of the induced polarization potential logging instrument comprises power supply electrodes, receiving electrodes and insulator rings, wherein 12 power supply electrodes are arranged at intervals in sequence at the upper portion, 24 power supply electrodes and 24 receiving electrodes are arranged in a staggered mode in the middle, 24 receiving electrodes are arranged at the lower portion, and all the electrodes are isolated through the insulator rings. The array-type electrode system of the induced polarization potential logging instrument achieves the function of pre-polarization by means of power supply-power off and measurement-power supply-measurement..., meets the stratum sufficient polarization time, achieves continuous measurement, and meets the speed-measurement upper limit which is 360
