| Abstract: | A new electromagnetic imaging scheme, including equipment, setting and image algorithm, was put forward. The surface to well setting, with an alternating current source on the surface, was adopted. A new two step inversion algorithm, namely inverse scattering current at first and then inverse electric conductivity, was employed. Through this method, the difficult nonlinear image equations are linearized, so electromagnetic imaging for any kind of electric conductivity contrasts can be done principally. |
