The MT-AMT set of instruments VMTU-10 allows solving the following geological prospecting tasks:
– based on geoelectric data to construct models of changes in the lithological characteristics of sedimentary rocks that are reservoirs of hydrocarbons;
– predict the boundaries of hydrocarbon reservoirs (reservoir – fluid seal) to highlight the most promising prospecting areas and adjust the locations of wells;
– determine the boundaries of ore bodies and occurrences when searching for solid minerals (solids) and water resources.
When solving the above problems, it is necessary to rely on a priori geological and geophysical data for the study region to increase the reliability of the forecast.
The VMTU-10 station is designed to carry out electrical exploration work using the MT-AMT method. The station’s Data Collection Unit is built on the basis of the edr-209 digitizer, manufactured by the English electronic company EarthData.
MT Station consist of:
- 5-channel Data Acquisition Unit VMTU-10
- 3 induction magnetic sensors of the IMS series
- 5 non-polarizing electrodes
- Antenna for satellite navigation system GPS, GLONASS
- 3 insulated shielded signal cables
- MT-AMT data quality control software – QMT and QMTview
- Software for processing MT-AMT data, 1D inversion program – VMTU1d
The depth of sounding ranges from several tens of meters to 10 km.
VMTU-10 digitally registers three mutually orthogonal components of an alternating magnetic field and two components of an electric (telluric) field in a wide frequency range from 0.001 to 1,000 Hz, which allows electrical exploration at depths from the first tens of meters to several tens of kilometers.
Magnetic induction sensors of the IMS series are precision converters of weak low-frequency magnetic fields into an analog electrical signal.
All sensors provide a maximum output voltage of ± 10 V at a supply voltage of ± 12 V.
