An imaging system to study the resistivity of rock is proposed. Firstly, the data acquisition characteristics of the display electrodes and the generation of resistivity images are introduced. Then the resistivity images of the sandstone samples measured by this system are given. The system can measure the non-uniform distribution of resistivity of rock samples in the laboratory and use the image to represent it. It can simulate the dynamic conditions of the strata and measure the change of resistivity while giving the pressure distribution in the phase-driven direction.
