一种井中瞬变电磁异常反演方法
A borehole TEM anomaly inversion method
摘要
Abstract
Borehole TEM is widely used in deep prospecting and has achieved fruitful results;nevertheless,qualitative and semi-quanti-tative interpretation is mainly used in borehole TEM data Interpretation at present,which restrictes the use and popularization of this method to a large extent. In view of this situation, the authors studied pure anomaly inversion of TEM based on current filament by u-sing genetic algorithm.With this method,we can accurately determine the size,dip and center coordinates of the in-hole or off-hole ab-normal body.The inversion results of sheet model forwarded by Maxwell software and measured data further prove the correctness and applicability of the algorithm.关键词
