A working parameter optimization method for 3D exploration of frequency domain conducted electrical method in exploration of abnormal areas

Abstract

A method for optimizing working parameters of three-dimensional prospecting by frequency-domain conductive electrical method for exploring anomalous areas. This method analyzes the distribution of the exploration anomaly area, the terrain level of the exploration area, the device type of the frequency domain conduction method, the number of channels for simultaneous power supply of the transmitter, the designed exploration depth, and the minimum length, width, and thickness of the electrical anomaly to be explored. Size requirements, the electrical difference between the electrical anomaly body to be explored and the surrounding rock, and the exploration time requirement coefficient, etc., obtain the optimized working parameters of the frequency-domain conduction method through specific formulas, such as the scope of the exploration area, point distance, Line distance, distance between power supply points, number of power supply points, at least the total number of optional channels for the receiver of the electrical instrument, etc. This method can obtain better working parameters of the frequency-domain conduction method, so that reliable exploration results can be obtained with more reasonable time and economic cost. This method is suitable for exploration work in exploration areas with many anomalous bodies and little known information.

Description

Technical field[0001]The present invention relates to an optimization of three-dimensional exploration working parameters of an exploration abnormality zone in an exploration of geophysical fields.Background technique[0002]At present, the working parameters of the exploration method of frequency domain transmission electrical method are generally the exploration staff based on their own experience and their general understanding of the exploration area. Due to the experience of each exploration staff, the general situation of the exploration area There are differences in the estimation, so that the working parameters in the exploration are strong, lack of a unified measure scale, which is easy to cause excessive or too little amount of exploration work. Excessive amounts of exploration work are prone to problem waste, high exploration cost, low efficiency and other issues; excessive exploration work is too easy to cause exploration effects to meet exploration target requirements, lo...

AI Technical Summary

Problems solved by technology

[0002] At present, the working parameters of the frequency-domain conductive electrical method are generally estimated and selected by the exploration staff based on their own experience and their general understanding of the exploration area. There are differences in estimates and other aspects, so the selection of working parameters in exploration is relatively random, and the lack of a unified measurement scale may easily lead to too much or too little exploration workload in design

Excessive exploration workload will easily lead to problems such as waste of workload, high exploration cost, and low efficiency; too little exploration workload will easily lead to problems such as poor exploration results that cannot meet the requirements of exploration targets, and loss of exploration targets.
