Description

technical field [0001] The invention belongs to the technical field of geophysical surveying, and in particular relates to a geophysical surveying system and method. Background technique [0002] Geophysical prospecting, referred to as geophysical prospecting, refers to the detection of geological conditions such as stratum lithology and geological structure by studying and observing changes in various geophysical fields. Due to the differences in density, elasticity, electrical conductivity, magnetism, radioactivity, and thermal conductivity of different rock formation media that make up the earth's crust, these differences will cause local changes in the corresponding geophysical fields. By measuring the distribution and variation characteristics of these physical fields, combined with known geological data for analysis and research, the purpose of inferring geological properties can be achieved. Geophysical exploration is based on the difference in physical properties of...

Problems solved by technology

[0004] The existing geophysical survey data is inaccurate; at the same time, the existing geophysical model is of low quality and low computational efficiency

[0005] In the existing technology, while filtering out the relatively large proportion of low-frequency components, it is impossible to retain the mid-high frequency components with rich image details. At the same time, there is a problem that the algorithm used is too dependent on the threshold; the existing technology is not conducive to the correct acquisition of earth gravity data, there is The impact of dynamic errors on the detection data; the existing technology is not conducive to real-time monitoring of the earth's seismic wave signal data, and the external environment interferes seriously with the seismic wave detector, reducing the sensitivity of the seismic wave detector to detect seismic signals
