In order to enhance the processing and interpretation efficiency with high density data of many adjacent sections on the same measuring line, this paper processes the multi-adjacent data sections through the data merging, 2D interpolation and inversion processing, at last the resistivity 2D inversion data of global section is output to file, and the map is drawn by Surfer software, which make data analysis and interpretation be convenient and prompt. The working efficiency is greatly improved. Through processing the practical data, it is verified that the processing software can be widely used to the practice.
