Geoelectric Method for Water Detection

- Mar 25, 2020-

The so-called electroelectric method is a method of measuring the visual resistivity of underground rocks using the electric field, which can be a method of drawing out the rock interface because of the different visual resistivity of the rock. The resistivity of water is very low, using the obvious electrical difference between water and surrounding rock to find the location of water is called electroelectric method to find water. There are many ways to find water by current method, the most common of which are the visual resistivity method and the visual polarization method (also known as the excitation polarization method). The theoretical basis for finding water by means of electricity is based on the use of this electrical difference in rock, when we use two electrodes on the ground to supply power to the ground, in the two poles formed an electric field, in which we use the instrument to measure the point and current strength of a certain point, and to find the point of the point of the point of the point of the point of the point of the point of the point of the point of the point of the point of the point of the point of the point of view of the resistivity. If there is water between the electric fields, a low resistance value can be displayed above the water level. It is by such means of electricity to find water.


1) The electrode laying is completed at once, reducing the interference caused by the electrode setting and the resulting measurement error. 

2) It can effectively measure a variety of electrode arrangement methods, so that you can obtain a wealth of information about the state of the geoelectric structure. 

3) Data collection and collection are all automated or semi-automated, not only fast collection speed, but also to avoid errors and errors due to manual operation. 

4) We can realize the real-time processing and offline processing of data, automatically draw and print various results drawing sgraphical lying according to needs, which greatly improves the intelligence of the resistivity method.
