Product Description
GD-5 Ultra-wideband Electromagnetic Equipment MT/AMT /CSAMT Gephysical Survey
GD-5 Ultra-wideband Electromagnetic Equipment is integrating high-frequency magnetotellurics (HMT) and audio-frequency magnetotellurics Magnetism (AMT) and magnetotellurics (BMT and MT) are An all-in-one broadband magnetotellurometer. The magnetotelluric method (HMT/AMT/BMT/MT) has a variety of observation methods and can provide a variety of qualitative interpretation parameters numbers, widely used in various medium and deep geophysical exploration fields. HMT/AMT/BMT/MT method can be used for 2D,3D profile or area exploration can also be carried out with fixed stations and mobile stations to achieve four-dimensional station-like continuity exploration.
GD-5 Ultra-wideband Electromagnetic Equipment also can be expanded to CSAMT, TEM, IP, etc.function), and can also carry out conventional seismic recording (including conventional refraction, reflection, micro-motion monitoring, etc.) to and other new geophysical method research.
Detailed Application about GD-5 Ultra-wideband Electromagnetic System
- Geology mapping to 1,000 meters and above for mining and mineral exploration.
- Mapping of hydrogeological features for groundwater exploration.
- Geothermal reservoir mapping to 2,000 meters depth.
- Shallow oil and gas exploration to 2,000 meters depth.
- Deep engineering and geotechnical applications, such as mapping of deep structures for future dam sites, characterization of potential integrity of nuclear waste repositories, visualization of geology.
- Deep mountain tunnel structure, etc.
- Excellent tool for academic research and teaching
