| 英文摘要 | Short-Offset transient electromagnetic method (SOTEM) theoretically has high detection accuracy. However, since the underground electrical structures are varied, the inversion scheme with only one specific model constraint is unable to cover various electrical structures. Therefore, we propose a robust SOTEM inversion scheme based on different model constraints, which can quickly obtain the inversion results with the characteristics of smooth, focused, and abrupt structure. The inversion scheme introduces the smooth functional, total variational functional and minimum gradient support functional to implement different regularization. After reconstructing different stabilizing functional, a unified inversion framework is utilized to obtain the solutions of inversion problems with different model constraints. The details of inversion procedure, such as forward modeling, iterative process, Jacobian matrix calculation and regularization parameter setting, are optimized to improve the efficiency and stability of SOTEM inversion scheme. Through a large number of different geoelectric models, the proposed optimized schemes are investigated to demonstrate the improvement on the stability and efficiency of inversion. Also, the inversion results with different model constraints are compared and analyzed. Thus, the stability, efficiency, and accuracy of the proposed SOTEM inversion scheme are verified. |
