摘要：

文中提出了一种新的瞬变电磁测量装置——框外测量测深法,该方法通过在框外20～25m处测量测深点代替框中心回线测深.其特点是在精确测量时,该方法可以很好地抑制发射线圈自感噪音影响,提高精测分辨率,并加深探测深度.通过与中心回线装置对比测量实验及实际生产应用,认为该装置应用效果好,值得在今后工作中推广应用.

Abstract:

In this paper we introduce a new kind of TEM sounding configuration: Outside-loop sounding configuration,which measures a sounding spot 20～25 meters outside the loop instead of directly measuring with central-loop sounding. The characteristic of the outside-loop sounding configuration is that during high-precision sounding survey,this method can massively avoid the influence from the self-inductance of the transmitter loop compared to central-loop sounding,thus, can raise the resolution and the exploration depth of the survey. By comparative tests with central-loop sounding configuration and application to a sounding survey carried out in Turpan-Hami Basin,Xinjiang,we find that the method is effective and shall be put in use in future.

Key words: TEM sounding, central-loop configuration, outside-loop sounding, Turpan-Hami Basin
