Problems solved by technology

[0003] The existing research and analysis on the geophysical magnetic field usually collects part of the magnetic field data in the area to be collected, and adjusts the data, that is, the actual measured local magnetic field changes are placed on the same magnetic field background for comparison and interpretation. There is a special chapter in the airborne geophysical prospecting specification, but because the method is too complicated and has been processed by filtering software and mathematical methods, the original measured data has changed, which in turn affects the relative relationship of the data and reduces the data. The authenticity of the data; and the lack of data acquisition also affects the accuracy of the data analysis of the geophysical magnetic field

Abstract

The invention provides a method for obtaining a big data obtaining preprocessing value of a geophysical field. The obtaining method utilizes collecting tools at a measuring area, a measuring line and a measuring point to obtain overall actually measured big data and the big data is calibrated and horizontally regulated to be the processing value. Compared with the prior art, the invention provides the method for obtaining the big data obtaining preprocessing value of the geophysical field, so that the authenticity of the originally actually measured data can be reserved, and the invariant relative relation of the data is ensured; the method is simple and efficiency, and ensures the quantity of the actually measured big data and improves the obtaining efficiency and accuracy of the big data preprocessing value, and thereby the accuracy of data analysis and research of the geophysical field is improved.

Description

technical field [0001] The invention relates to the field of geophysical magnetic field measurement, in particular to a method for acquiring preprocessed values ​​of large data of geophysical magnetic field. Background technique [0002] The study of the geophysical magnetic field is carried out after data processing of the data measured by the field value of the magnetic field in the formation rocks. In order to improve the accuracy of the analysis, it is necessary to obtain enough big data of the magnetic field and retain the authenticity of the big data while converting it into an analyzable preprocessed value. [0003] The existing research and analysis on the geophysical magnetic field usually collects part of the magnetic field data in the area to be collected, and adjusts the data, that is, the actual measured local magnetic field changes are placed on the same magnetic field background for comparison and interpretation. There is a special chapter in the airborne geo...
