Embodiment Construction

[0053] The technical solutions in the embodiments of the present invention will be apparent from the embodiments of the present invention, which will be described below, as will be described herein, not all of the embodiments of the invention, not all of the embodiments of the invention. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0054] The three-dimensional resistivity of the high-density electrical method is similar to the non-uniform measurement network, and there is no need to follow the high-density electrical method Wenner or the equidistant quadruple array, as long as the relative position or coordinate of the electrode is determined. It can form unevenly measured network data format for three-dimensional inversion, and the electrical scavenger can be aligned or inequalized. It is only too sparse, which will increase the three-dimensional inversion geolog...

Abstract

The invention discloses a three-dimensional resistivity sounding application method based on a high-density electric Wenner device, which uses a high-density 2D resistivity meter Wenner device and a large mesh and large pole distance electric sounding profile to form a three-dimensional resistivity data body , the electrode arrangement was converted into a symmetrical quadrupole device, and then constructed into an uneven surveying network, and the least square method was used to carry out three-dimensional inversion. This observation method increases the detection depth, reduces the cost, and effectively reflects the spatial characteristics of geological bodies , providing detailed information for drilling layout.

Description

Technical field [0001] The present invention relates to the field of geological exploration techniques, in particular a three-dimensional resistivity, a three-dimensional resistivity, a three-dimensional resistivity, a three-dimensional resistivity, a three-dimensional resistivity. Background technique [0002] High-resolution geological mineral three-dimensional exploration is the goal of electrical development, collecting high-resolution electrical method three-dimensional observation data, and three-dimensional inversion is the key to measurement area resistivity 3D fine structure detection. At present, the three-dimensional observation method of resistivity is important aspects of research. It is not only related to the efficiency and cost of field observations, but also related to the resolution and inversion effect of the data. [0003] The existing information shows that the three-dimensional inversion of common resistance can only meet the shallow three-dimensional explor...
