The Research on the IP Parameters Extraction from MT Data

In polarized layer the formation resistivity is a complex number that depends on the frequency, but in conventional MT method the formation resistivity is usually considered as a real parameter that is independent of the frequency. Based on Dias model, Studying the basic theory and method of Extract the IP parameters from MT data, Giving a new method to calculate wave impedance at different frequency; meanwhile, the detail formula and algorithm for one-dimensional layer earth are derived. Joining IP method with MT method to inverse geoelectric parameters in the MT method is suggested.
