The simulation results demonstrate the rightness and efficiency of FEM. Based on the studies above, the detective characteristics of FMI are examined, a few device structural parameters are numerical analyzed and optimized. The response of each type of formation model is simulated, and gray-scale images are used to express the resistivity results. Adopting 8 electrodes manner to measuring inclined bed, a full-bore resistivity image is obtained, and the relations between the image and the inclined bed are pointed.
