At present, geophysical exploration methods and technologies mainly include the following:

1.gravity exploration

Gravity prospecting refers to a method of geological prospecting that uses the change in surface gravity acceleration value caused by the density difference between various rock masses and ore bodies that make up the earth's crust, as long as the exploration geological body and its surrounding rock mass have a certain density. If there is a difference, you can use a precise gravity measuring instrument to find out the gravity anomaly. Then, combined with geological and other geophysical prospecting data in the working area, qualitative and quantitative interpretations of the gravity anomaly can be made to infer the burial of ore bodies and rock formations with different densities below the overburden, and then find out the location and geological conditions of hidden ore bodies structure.

2.Magnetic Prospecting

Magnetic prospecting refers to the fact that rocks and ores in nature have different magnetic properties, which can generate different magnetic fields, which cause changes in the earth's magnetic field in local areas, resulting in geomagnetic anomalies. Using instruments to discover and study these magnetic anomalies, and then to find magnetic ore bodies and study geological structures.
3.Electrical prospecting

Electrical prospecting refers to a geophysical prospecting method for prospecting and studying geological structures based on the differences in the electrical properties of rocks and ores. It observes artificial and natural electric fields or alternating electromagnetic fields through instruments, and analyzes and explains the characteristics and laws of these fields, so as to achieve the purpose of prospecting and exploration

4.Seismic exploration

Seismic exploration is the use of artificially excited seismic waves, by laying out survey lines on the ground, receiving its reflected waves, and then performing some processing, so as to reflect the underground structure and serve the purpose of searching for oil and gas and other exploration purposes.

5.radioactive survey

Radioactive surveying is also known as radiometric surveying or "gamma method". With the help of α, β, γ rays released by the decay of natural radioactive elements in the earth’s crust, they will produce special physical phenomena such as dissociation and fluorescence when they pass through the material, and use special instruments to measure the intensity of these rays or other geological problems. . Radioactive prospecting is also an auxiliary means to find deposits of rare elements, rare earth elements and polymetallic elements that coexist with radioactive elements. Radioactive geophysical methods include gamma measurement, radiation sampling, gamma logging, jet gas measurement, track measurement and physical analysis.

6.Logging

Well logging is also called geophysical logging. It is a method of measuring geophysical parameters by using the electrochemical properties, electrical conductivity, acoustic properties, radioactivity and other geophysical properties of rock formations. It is one of the applied geophysical methods. During oil drilling, logging must be carried out after drilling to the designed depth, also known as completion electrical logging, to obtain various petroleum geology and engineering technical data as raw data for completion and development of oil fields. This logging habit It is called open hole logging. The second series of logging after the casing is run in the oil well is customarily called production logging or development logging. The development of production logging has generally experienced analog logging, digital logging, numerical control logging, imaging logging these four stages of logging.

7.geothermal exploration

Geothermal resource exploration refers to geological, geophysical and geochemical comprehensive surveys, drilling and testing, sampling testing, dynamic monitoring and other geological work to find out geothermal resources in a certain area. According to the progress of exploration work, it can be divided into investigation, pre-feasibility exploration, feasibility exploration and mining stages
