Zusammenfassung:The invention provides a rock resistivity function description method, which comprises the following steps: selecting at least two rock samples of the same type of rocks, and carrying out a saturated water experiment and a centrifugal experiment on the rock samples, measuring pore water resistivity of the rock sample, rock resistivity corresponding to saturated water saturation and rock resistivity under different partial water saturation; respectively obtaining a first function coefficient and a second function coefficient of a saturated water rock resistivity description function equation according to the rock porosity, the pore water resistivity, the rock resistivity corresponding to the saturated water saturation and the rock resistivity under different water saturations; according to the third function coefficient of the relation equation of the partial saturated water rock resistivity and irreducible water saturation corresponding to different effective water saturation and the fourth function coefficie
