大地电磁测深因成本低、勘探深度大而获得地球物理工作者的青睐,同时其不受高阻层屏蔽并对高阻层下的低阻层有较好的反映,这些优势使得MT在地热资源探测的应用中变得越来越重要。本文通过对测区的5条MT剖面资料的精细反演并结合该地区的地质及重磁资料对处于火成岩背景条件下的水热型地热资源进行勘查。以岩石物性为基础,通过地质资料分析和MT层状介质连续反演、重力-电法综合解释进一步了解该地区地质特征,结合该地区已有的地热资源和MT资料研究成果对有利勘探区进行评价。
Because of its low cost and deep exploration depth, geomagnetic sounding is favored by geophysical workers, and it is not shielded by high-resistivity layer and has a good reflection of low-resistivity layer under high-resistivity layer. These advantages make MT in geothermal The application of resource exploration becomes more and more important. In this paper, the hydrothermal geothermal resources under the background of igneous rocks are investigated by the fine inversion of 5 MT profile data of the survey area and the geological and gravity-magnetic data of the area. Based on the petrophysical properties, through the geological data analysis and MT layered media continuous inversion, the comprehensive interpretation of gravity-electric method to further understand the geological features of the area, combined with the existing geothermal resources and MT data research results in the region for the favorable exploration area Evaluation.
