The utility model relates to a novel double-lateral electrode system. The double-lateral electrode system comprises an upper casing, a lower casing and a core shaft, wherein, the electrode system comprises a group of metal electrodes and glass reinforced plastic spacer sleeves; the metal electrodes and glass reinforced plastic spacer sleeves are sleeved outside the core shaft and are in threaded connection through the upper casing and the lower casing, so as to form a whole body; a pressure balancing piston compensation structure is adopted in the double-lateral electrode system; all the metal electrodes are independent each other, and are symmetrically distributed in longitudinal direction with a middle main electrode as the center; and one end of an upper pre-amplification circuit and one end of a lower pre-amplification circuit are connected with an internal metal electrode through a sealed long inserting pin, and the other ends thereof are connected with an external line through an inserting pin.
