全程瞬变电磁系统的浅层探测实验研究

Study of the Experiments of All-time Tramsient Electromagnetic System for Shallow Survey

介绍了全程瞬变电磁ATTEM系统的基本原理及组成。采用该系统在长春市秦家屯进行了模型实验和活断层勘探实验,并与常规瞬变电磁系统ATEM-Ⅱ的勘探结果对比。实验结果表明,ATTEM系统具有很好的浅层探测能力,在该地区其最浅有效探测深度为地下1~2m。

The basic principle and structure of All-time transient electromagnetic(ATTEM) system are introduced.Model experiments and field experiments were performed in Changchun Qinjiatun using ATTEM,the interpretation results show that ATTEM has better shallow sounding ability than traditional transient electromagnetic system,such as ATEM-II,and the least sounding depth of ATTEM in the area is about 1 to 2 meters.
