Abstract

The invention provides a geophysical data fusion and imaging method, a medium and a device. The method comprises a step of performing detection with different geophysical prospecting methods in each detection area and collecting multiple sets of original data, a step of preprocessing measured data of each set such that the requirements of data accuracy and conversion calculation are satisfied, a step of converting each set of preprocessed measured data into a reflection coefficient sequence that can be used for fusion, a step of calibrating reflection coefficient sequences based on different coordinate systems into a unified spatial coordinate system, and a step of selecting a data fusion method to fuse reflection coefficients according to digital characteristics of data corresponding to different geophysical prospecting methods, converting multiple sets of reflection coefficient sequences into one set and performing corresponding imaging to obtain a geological information result afterthe fusion of various geophysical prospecting data. According to the invention, the defect that the analysis of some abnormal bodies in the existing geophysical interpretation is not comprehensive, the interpretation accuracy is low and the efficiency is low is overcome, the fusion imaging of different methods and different measurement line data in three-dimensional space can be carried out, andthe comprehensive interpretation precision is effectively improved.

Description

technical field [0001] The disclosure relates to a geophysical data fusion and imaging method, medium and equipment. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In geophysical exploration, with the increase of the complexity of the actual problems on site, the method of effectively combining two or more geophysical exploration methods to jointly complete the detection task has become a new development direction of geological exploration. However, when multiple geophysical prospecting methods are used for joint detection, the interpretation process is often explained separately first, and then compared with each other. Such a comprehensive interpretation method is often just a simple combination analysis without considering the correlation between data. The analysis of some anomalous bodies is not comprehensive enough, and the interp...
