| Summary | In order to meet the requirements of deep oil and gas exploration, groundwater and environmental monitoring, and geothermal exploration, high-precision and fast 3D inversion methods need to be developed for the Transient Electromagnetic method with electrical sources. Traditional methods of constructing initial models are time-consuming and subjective, posing significant challenges to inversion efficiency and data interpretation. Therefore, the rational construction of initial models is an urgent issue that needs to be addressed in current 3D inversion of Transient Electromagnetic methods. This study establishes a forward modeling under geological conditions, conducts inversion calculations using both a uniform half-space initial model and a one-dimensional resistivity-guided initial model construction method, and discusses the computational effects of both approaches. The results indicate that the inversion with a constrained initial model yields good results, providing an effective means for processing and interpreting actual data. |
