Disclosed is a method for removing a borehole fluid effect in a borehole electrical resistivity survey including a borehole. The present invention includes the steps of: calculating the borehole fluid effect considering the electrical resistivity distribution around a hollow wall in the borehole; modeling an underground space model around the borehole and calculating the electrical resistivity distribution for the underground space by reflecting the calculated potential change by the borehole fluid effect in inversion operation of the electrical resistivity. According to the present invention, the present invention has an effect of quantitatively calculating the borehole fluid effect in the analysis of borehole electrical resistivity survey data.;COPYRIGHT KIPO 2017
