| 英文摘要 | Apparent resistivity has played a significant role in electromagnetic exploration and is able to be used for preliminary interpretation. Multi-channels transient electromagnetic method defines the apparent resistivity using the peak time of earth impulse response. However, traditional method evaluating peak-time apparent resistivity need to recover the entitle earth impulse response. In this paper, a new frequency-domain ratio method is proposed by studying characteristics of both the impulse response and its spectrum. Apparent resistivity is obtained by calculating the peak time of the general spectrum using reference spectrum and scaling factor between the reference spectrum and the general one. Only single-point spectrum is needed to get the peak time, instead of estimating the entitle earth impulse response. In practical, multiple-points spectrum can be exploited to obtain the averaged apparent resistivity. The results from synthetic and field data show that frequency-domain ratio method gives reasonable apparent resistivity in one dimensional media. |
