In a mining area in Northwest China, the induced polarization method and magnetotelluric method are used for joint exploration. The same set of equipment collects data at the same time and at the same points, so as to improve the acquisition efficiency, and complete large depth + shallow high-resolution exploration at the same time. The induced polarization method has very high resolution in the shallow part, and can obtain the full waveform polarizability data, which can clearly reflect the underground electrical characteristics within 600m; The deep exploration by magnetotelluric method reflects the deep rock mass and structural characteristics. Combined with the shallow IP section, the underground electrical structure can be inferred more comprehensively.
Construction method:TDIP bilateral three pole,50m point distance;MT vector measurement, 200m track distance.
In the detailed
magnetotelluric survey of the structural development section of Gaoligongshan
tunnel of Darui railway, the terrain within the survey line is seriously cut
and the vegetation is dense. Node distributed acquisition is adopted to give
full play to the advantages of ultra-small volume of equipment and improve the
acquisition efficiency. The exploration depth is 1000m, and the electrical
characteristics of magnetotelluric profile are basically consistent with
geological and borehole data. The spatial characteristics of geological
inferred faults in the deep are revealed, and the electrical characteristics of
surrounding rock in multiple lithologic interfaces and tunnel elevations are
MT vector measurement, acquisition time 2 hours, electric track distance
20-40m, magnetic track distance 100m.
CASE：Active Source Sesmic and HVSRBOTH System Q&A
Q1: what is the uniqueness of both compared with traditional
The node unit contains 3 (2 ~ 4 optional) 32-bit high-precision
acquisition channels, which are compatible with sensors of different types and
manufacturers. After the field layout is completed, electromagnetic method,
three-dimensional induced polarization method and active source / passive
source seismic data acquisition can be carried out at the same time. In one
layout, multiple geophysical parameters can be collected to facilitate the
simultaneous construction of multiple methods.
Q2: what scenario is suitable for using the both system?
1. Work areas requiring shallow high-resolution and deep electrical
2. Work areas where the interpretation accuracy of single method is
not enough and comprehensive verification of multiple methods is required
3. Large area three-dimensional induced polarization exploration
4. Complex terrain and low efficiency of conventional construction
Q3: why is it efficient?
1. A variety of geophysical parameters are obtained in one layout,
which solves the problems of equipment replacement and repeated construction in
different methods; Any combination of magnetotelluric, induced polarization
method and seismic method;
2. The node layout mode is adopted, and the weight of a single host
is light. More than 12 sets can be operated by a single person in the field,
and the pole layout efficiency is several times better than that of traditional
Q4: how to deal with the collected multi parameter data?
Equipped with special data preprocessing software rocket, it
integrates earthquake, three-dimensional induced polarization method, frequency
domain induced polarization method and electromagnetic method, and can
efficiently manage the original data, preprocess the data and input and output
the data. The main functions of the software include: original time series
management, data inspection, time domain filtering and preprocessing,
three-dimensional layout design, induced polarization data fusion, IP
attenuation curve extraction, amplitude and phase extraction, seismic data
preprocessing and inspection, seismic data extraction, section display, etc.
Q5: how to deploy in the field when collecting multiple parameters?
Any combination of various methods, such as MT + TDIP, MT + sip,
earthquake + MT, earthquake + sip, etc
