The invention provides a universal pole plate sidewall contact device which comprises a main base body and a plurality of sidewall contact arms symmetrically mounted in the axial direction of the mainbase body, each sidewall contact arm comprises a pole plate module, a rotating main arm and a sliding main arm, two groups of sidewall contact arms are arranged at intervals in the axial direction ofthe main base body, each group comprises four sidewall contact arms, and two groups of sidewall contact arms are staggered in the circumferential direction; the pole plate module comprises a rectangular hollow frame, a left connector and a right connector which are oppositely installed at the two ends of the frame, and a block-shaped top plate which is installed in the frame and can be inclined relative to the directions of the left connector and the right connector, the bottom face of the top plate faces the main base body, the top face of the top plate protrudes out of the frame on the horizontal plane, and the top face is in an arc shape with the middle higher than the periphery. According to the invention, the pole plate module has angle adjustment in four directions, so that the adaptability to well walls in different shapes is greatly improved, the stability of the whole main base body supported by the sidewall contact arms is further improved, the instrument test is facilitated, and the test precision is improved.
