| Abstract: | A new method with the use of Lambert W Function is presented to solve apparent conductivity and apparent dielectric constant in electromagnetic high frequency electromagnetic well logging. Theorehcal analysis and numerical experiment show that this method has higher precision and calculating efficiency than traditional approach, in which it is necessary to solve complicated non-linear .equation system. Compared tO Chart method, this method needn't pre-calculate a lot of charts while it has higher precision. |
