Array type electrode system for induced polarization potential logging instrument

The invention provides an array type electrode system for an induced polarization potential logging instrument, belonging to the field of a measuring tool in cooperation with a logging instrument. The array type electrode system comprises current electrodes, receiving electrodes and insulating rings. The 12 current electrodes at the upper part are sequentially arranged with one another at intervals; the 24 current electrodes at the middle part and the 24 receiving electrodes are alternately arranged with one another; and the 24 receiving electrodes at the lower part are isolated from one another by the insulating rings. The electrode system provided by the invention realizes a pre-polarization function, and meets the abundant polarization time of the stratum in the manner of power supply, power failure measurement, power supply, measurement, and the like. The continuous measurement can be realized, and the speed measurement upper limit 360m/h can be met. Due to the assembly of 36 measurement points, the overa
