| Abstract: | High-frequency induction logging provides rich log data with different probing depths and different frequencies.After inversion,calculated are undisturbed formation resistivity and invaded zone resistivity,as well as relative dielectric constant and invasion radius.Inversion algorithm of high-frequency induction log data is more useful.Nonlinear iterative technique is used to solve inversion problems in high-frequency induction logging.Firstly,an initial formation model is supposed previously,and then the f... |
