Exemplified by some results obtained from the electric imaging detection of active faults in Zibo City,this paper described the method for geological interpretation and analysis of images from the electric imaging technique,and studied the input impedance range of the instrument for urban active fault detection as well as some problems which deserve attention in data processing and inversion.

The electric imaging technique of vertical line power depends on supplying power by cased well, which not only is feasible for field operation, but also can greatly increase the surveying depth and imaging precision and implement operation without affecting normal production of oil well.

In exploration of a shallow active fault in urban area,seismic reflection survey and electrical imaging are the two main geophysical tools.

Genetic algorithm in solving ill-posed equations of 2D electromagnetic imaging;

This paper mainly deals with the sensitivity of the well surface electromagnetic imaging, including its features in different observation components, different positions and different frequencies.

The electromagnetic imaging techniques have received considerable attention in the past few years, as they can be suitable for a number of important applications such as medical science, nondestructive detection and so on.
