NON-POLARIZABLE PROBE AND SPECTRAL INDUCED POLARIZATION LOGGING DEVICE INCLUDING THE SAME

摘要

A non-polarizable probe and a spectral induced polarization logging device for a borehole including the same are provided. The non-polarizable probe includes a main body 5 having an internal space, and a set of electrodes disposed in the main body. The electrodes include a current electrode to supply electric current to a target and a potential electrode to measure a potential induced from the target. The electrodes are spaced a predetermined distance from each other. Each of the electrodes includes an inner casing having an internal space, a lead rod wound around the inner casing, an outer casing covering the inner casing 10 wound with the lead rod, and a filling material filling the space between the outer casing and the inner casing. _200 100 12C1P1P21----------4 12 l P P213 411
