Multi-Channel Electrical Geophysical Exploration Instrument For Underground Detection


Introduction


What is the geophysical exploration?

There are many methods of geophysical exploration. Electrical geophysical exploration is a very important and commonly used measurement method.

The method of understanding the rock condition of underground strata by observing the difference in the electrical conductivity of different rocks is called electrical geophysical exploration. Sedimentary rocks associated with oil and gas tend to have good electrical conductivity (low electrical resistivity). Electrical prospecting can be used to find and identify such strata. Electrical prospecting is an important prospecting method in geophysical exploration.


Application


It can be conveniently used with domestic common high density electrical processing software to make the interpretation more convenient and straight view. The system can be widely used in energy exploration, urban geophysical exploration, railway and bridge exploration, metal and non-metal exploration,mineral resources exploration and other aspects, also used to find groundwater, to determine the dam foundation and flood control levees hidden danger location in hydrology and engineering geology exploration, it can also be used in geothermal exploration.


The system takes WDJD-3A multifunctional digital DC geophysical exploratioon instrument as the measurement and control host, which can be selected by: WDZJ-4, WDZJ-120 multi-channel electrode converter, centralized high-density cable, electrode, to achieve centralized 2D resistivity measurement.
