The design of the natural electric field well and water finder is mainly based on the theory of electromagnetic field and the theory of earth electric field. Electromagnetic field theory is a central theory in physics, which describes the fundamental properties of electric and magnetic fields, as well as the interrelationships between them. In the field of earth science, electromagnetic field theory is widely used in the earth's magnetic field, electromagnetic induction, conductivity determination, etc.
The terrestrial electric field refers to the electric field on the earth's surface, which is mainly caused by the uneven distribution of electrical conductivity in and on the earth's surface. The change of the geodetic electric field is closely related to the underground geological structure and hydrogeological conditions, so the information of the underground geological body can be obtained by observing the change of the geodetic electric field.
First, the design principle.
The core of the design of the natural electric field well finder is to select the frequency to accept the audio electric field electric field signals of multiple frequencies. By selecting different frequencies, observations can be made for different geological formations. For example, lower frequencies are mainly better for deeper formations, while higher frequencies are better for shallower formations.
In terms of signal processing, the natural electric field well drilling and water finder adopts weak signal detection technology. This technology can amplify, filter, selectively detect, integrate, etc., and process the weak audio geodetic field signal, and then adjust the signal into a digital signal for analysis. This processing method can effectively improve the signal-to-noise ratio of the signal, so as to obtain more accurate geological information.
Second, the field of application.
The natural electric field well drilling and water finder has a wide range of applications in geological exploration, hydrogeological survey, environmental geological assessment and other fields. For example, in the field of water searching, the distribution and depth of underground aquifers can be inferred by observing the variation of the geodetic electric field. In the field of geological structure research, the natural electric field well finder can help us understand the distribution, thickness, lithology and other information of the formation.
3. Technical characteristics.
1.Multi-channel and multi-mode data acquisition: The natural electric field well drilling and water finder adopts multi-channel and multi-mode data acquisition technology, which can collect multiple frequencies of electric field signals at the same time, which improves the efficiency of data acquisition.

3.Strong anti-interference ability: In hardware design and software development, a variety of reliable technologies are adopted, so that the anti-interference ability and the stability of the system have been strengthened.
4.Automatic mapping water finder: With the magnetotelluric field as the field source, based on the conductivity difference of different geological structures underground, the geological structure and changes are studied by measuring the change law of electric field components of different frequencies, and the changes of geological structures of groundwater resources are scientifically searched for and displayed in real time through the curve chart. A simple one-button operation automatically generates a geological profile map, getting rid of cumbersome computer mapping. On-site, you can quickly understand the geological structure through the automatically generated curve and profile diagram, and analyze specific information such as aquifers, fractures, faults, and karst caves.
5.Widely used: The instrument is widely used in plains, hills, mountains, plateaus, basins and other different terrains to quickly analyze geological structure changes, determine well locations, aquifers and aquifer depths.
Natural electric field drilling and water finder is an advanced geological exploration instrument based on electromagnetic field theory and earth electric field theory. It has the characteristics of multi-channel and multi-mode data acquisition, automatic analysis and processing, strong anti-interference ability, etc., and can be widely used in geological exploration, hydrogeological survey, environmental geological assessment and other fields. By observing the variation law of the geodetic electric field, the information of underground geological bodies can be obtained, which provides important technical support for geological structure research and water search.
