Study On Application Effect Of Wide-Field Electromagnetic Method In Qinghai Region

Wide-Field Electromagnetic Method is a new deep-geophysical geophysical exploration technology and theory produced under the background of deep-prospecting strategy.It is currently being promoted across the country and is widely used in geophysical exploration in solid minerals,water resources and energy.The purpose of this paper is to analyze and sort out the actual prospecting experience of the wide-area electromagnetic method in Qinghai Province in recent years,and to summarize and evaluate its effectiveness.The article mainly analyzes and summarizes the effectiveness of the method by combining theoretical elaboration and actual case analysis.First,the Wide-Field Electromagnetic Method is introduced in the history of the development of the frequency-domain electromagnetic method to introduce the basic theory;secondly,a series of work processes from the construction of the Wide-Field Electromagnetic Method to the formation of geological results are introduced.The related inversion work of Wide-Field Electromagnetic Method is the most critical work in the process of turning Wide-Field Electromagnetic Method into geological results.Finally,it includes shale gas,metal ore,dry hot rock,groundwater,brine brine in Qinghai Province.The practical work cases of the wide-area electromagnetic method in different fields are summarized from the positive and negative aspects of the success and failure.The results of the wide-area electromagnetic method under different geological-geoelectric conditions and different mineral species are evaluated.The selection and implementation of the wide-area electromagnetic method provides some lessons that can be used for reference in Qinghai Province.
