Abstract

WDZS-3 Multifunctional electrical water detector is the basic 1D VES device of geo-electrical method, with functions of SP survey and 1D Resistivity sounding. The electrical method for groundwater exploration is the most economic, effective and widely used.WDZS-3 is a special geo-electrical instrument for electrical underground water prospecting with the most parameters, the most function, and the most advanced performance at the present time.

Working principle

Geological medium. The method is based on the estimation of the electrical conductivity or resistivity of the medium. The estimation is performed based on the measurement of voltage of electrical field induced by the distant grounded electrodes(current electrodes).

Applications

Energy & Mining: Shale gas reservoir mapping, ore body localization.
Urban Engineering: Underground utility detection, tunnel stability assessment.
Hydrology & Environment: Dam leakage inspection, contaminant plume tracking.
Geohazards: Landslide structure profiling, fault zone analysis.

FAQ

In gravity exploration (SI), what is the unit of gravity? How to convert gravity units between SI and CGS?

What are gravitational field and gravitational potential?

What is the normal gravity field of the earth? What are the rules for the change of the normal gravity field with latitude and altitude?

① The normal gravity field of the earth: Assuming that the earth is a rotating ellipsoid (reference plane), the surface is glossy, the internal density is uniform, or it is distributed in concentric layers, the density of each layer is uniform, and the deviation of the shape of the ellipsoid from the geoid is very small, then the gravity field generated by the earth is the normal gravity field.
② The normal gravity value is only related to the latitude, the smallest at the equator and the largest at the poles, with a difference of about 50,000 g.u.; the rate of change of the normal gravity value with latitude is the largest at 45° latitude, and zero at the equator and the poles; the normal gravity value decreases with increasing altitude, and its rate of change is -3.086 g.u.. The main feature of the long-term change is the "westward drift" of the geomagnetic elements, both the dipole field and the non-dipole field drift westward, and have a global nature.
