Abstract

Based on the forward theory of loop-source TEM, the all-time apparent resistivity is obtained by calculation. Because of the jumping feature in the early-late apparent resistivity when using induced electromotive force, this paper uses transient electromagnetic field to calculate the all-time apparent resistivity, and obtains the continuous and higher precision value. Two methods are used in inversion imaging, one is the smoke-ring, and the other is fast approximate inversion. According to the research, the smoke-ring is easier to achieve, but the fast inversion can reflect the relationship between depth and conductivity better, the result can be a good reference for the research of longitudinal variation of stratum structure.
