[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

The present invention provides a method for obtaining the preprocessing value of large geophysical magnetic field data. The obtaining method uses collection tools to obtain all the measured large data in the measurement area, measurement line and measurement point, and then adjusts the calibration level of the large data to the preset value. processing value. Compared with the prior art, the present invention provides a method for obtaining the preprocessing value of large geophysical magnetic field data, which preserves the authenticity of the original measured data and ensures that the relative relationship of the data remains unchanged. The method is simple and efficient, It ensures the quantity of measured big data and improves the efficiency and accuracy of big data preprocessing value acquisition, thereby improving the accuracy of geophysical magnetic field data analysis and research.
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...
