Research of Interpretation System of TEM Tomography

In order to improve the distinguishing ability of TEM, a study of interpretation system of TEM tomography has been finished in this paper. The law of propagation of electromagnetic wave and seismic wave in medium and the response of TEM far-field have been fully discussed. According to the similarity between the propagation of magnetic dipole source TEM field and reflected-seismic wave, it is proposed to explain TEM data with the pseudo-seismic interpretation. The forward and inversion calculated result of theoretical model examples indicates that the theory is right; the processed results of the field data demonstrate that this method is useful and practical.
