Description
Induced polarization is mainly produced by the electron-transfer effect of the polarization current, which occurs primarily at the contacts between ferrous metallic and semiconducting metallic mineral particles.
This tool uses two outer measuring electrodes to energize a controllable alternating current that passes through the formation. After the external power is removed, two inner electrodes of the probe measure the voltage variation with time. The integral area under the voltage–time curve is a measure of the chargeability.
The tool can measure 0.4 m potential resistivity, 1.2 m potential resistivity, 1.4 m gradient resistivity, spontaneous potential, and 0.4 m induced potential. Its supply current, supply waveform, signal-input attenuation, and induced-potential sampling time can all be adjusted and controlled by the surface acquisition computer.
It is mainly applied in metallic-mineral and hydrological logging.
