井中瞬变电磁法在深部找矿中得到广泛应用并取得丰硕成果，然而解释技术目前仍以定性和半定量为主，这在很大程度上制约了该方法的运用和推广。鉴于此，笔者采用遗传算法开展了基于等效涡流的井中瞬变电磁纯异常反演研究，反演以导体内感应电流环为对象，能够准确地确定井中或井旁异常体的尺度、倾角、中心坐标等参数。对Maxwell软件薄板模型的正演数据和实测数据的反演结果进一步验证了算法的正确性和适用性。

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.
