The invention discloses an electrode measurement influence automatic correction through casing resistivity logging method and device. Two potential difference meters with different internal resistance are used for measuring the potential of two meters in an interactive power supply mode, and apparent formation resistivity is calculated according to the obtained potential of a metal casing at a measurement point. Therefore, the influence of electrode measurement environment factor change on measurement results can be automatically eliminated by the electrode measurement influence automatic correction through casing resistivity logging method and device.
