Abstract

Disclosed in the invention is a combined inversion technology of a high-density resistivity method and a transient electromagnetic method. The combined inversion technology is implemented as follows: step one, collecting shallow resistivity values from a shallow burned area with the depth less than Xm and a goaf by using a high-density electrical method; step two, collecting deep resistivity values from a deep burned area with the depth larger than Xm and a goaf by using a rectangular loop source transient electromagnetic method; and step three, carrying out approximate three-dimensional inversion interpretation on the combined shallow resistivity values and g deep resistivity values to obtain a high-precision underground fracture electric interpretation result. According to the combined inversion technology disclosed by the invention, the resistivity data obtained by the high-density resistivity method and the resistivity data obtained by the transient electromagnetic method form a unified three-dimensional data volume to obtain visible transverse, longitudinal, and horizontal slices of the stratum; and quantitative interpretation is carried out on the unified three-dimensional data volume.

Description

technical field [0001] The invention relates to the computer technology of data soft processing, especially the joint inversion technology of high-density resistivity method and transient electromagnetic method. Background technique [0002] The high-density resistivity method can quickly and accurately provide the geological interpretation map of the measured geoelectric section through the corresponding program processing and automatic inversion imaging of various parameters, thereby improving the effect and work efficiency of the resistivity method. The high-density resistivity method combines the effects of the profile method and the electrical sounding method, and has the advantages of small point spacing and high data collection density. Compared with the conventional resistivity profile method and bathymetry method, it can not only provide The variation trend of electrical properties along the horizontal direction at one depth can also reflect the electrical variation...
