Abstract:About the inversion of 1-D full CSAMT data, the paper discusses an inverted approach used in layered strata.The approach combines the network parameter method with layer-stripped method and uses two controlling parameters as a constraint that makes the inverted results better.Combination of the network parameter method with layer-stripped method is characteristic of fewer inverted parameters and free from relying on initial model.The paper gives four three-layer and two five-layer numeric models to implement tests, which show the approach can rebuild the layered structures of models and have certain ability for suppression of noises.Using the inversion for real data of layered distribution, the inverted results are coincidence with geologic data basically.The approach avoids the error brought by near-field correction, which provides a basis for the feasibility of inversion of 1-D full CSAMT data.
