Embodiment 1
[0113] This embodiment is an example of high-density electrical method. In the field measurement of this embodiment, the DUK-2 high-density electrical instrument measuring system produced by Chongqing Geological Instrument Factory is used. The instrument is composed of a multi-channel electrode converter DUK-2 and a multifunctional direct current instrument DZD-6. , the observation parameter is the apparent resistivity ρs, and the cross-section electrodes are laid out at one time during the field measurement, and the acquisition parameters and device parameters of the instrument are set, then the measurement and storage of the apparent resistivity value of the cross-section can be performed automatically; data recovery to the laptop.
[0114] This field wiring method adopts the classic Wenner AMNB device (that is, the symmetrical quadrupole device method, WN). As shown in Figures 6 and 7, Figure 6 is an overall effect diagram of the sixth block of a certain work area accordin...
Embodiment 2
[0118] This embodiment is an example of magnetotelluric sounding. In the field work of this embodiment, the most advanced magnetotelluric depth sounder GMS-06 produced by Metronix, Germany, which can not only process in real time, but also record and store the original time series, is used for data collection. There are six instruments in total, including two five-component systems and four two-component systems. During work, the six instruments are used at the same time, relying on the precise GPS system that comes with the instrument for synchronous recording.
[0119] As shown in Figures 9 and 10, Figure 9 is an overall effect diagram of the MT data measurement results in a certain work area according to the second embodiment of the present invention, and Figure 10 is a cutting effect of the MT data measurement results in a certain work area according to the second embodiment of the present invention picture.
[0120] As shown in Figures 11 and 12, Figure 11 is a statistic...
