The complex resistivity logging is introduced briefly. The mathematic model of the logging is established. The numerical simulation program of the complex resistivity logging is written according to the FEM. The program is proved to be correct and used to calculate the environmental correction charts. It is also used to determine the investigation characteristics of the logging tool, responses of frequency and formation which contains oil and water. The study indicated that the complex resistivity logging is viable, and can be used to identify oil bearing formation easily. The complex resistivity logging tool has a similar investigation characteristic as the dual-laterolog tool.
