摘要
为了探查承德机场临空区热储条件,选定有利靶区,利用 6 条可控源音频大地电磁测深剖面,进行数据处理、分析和反演,获得可靠的二维电阻率模型.根据测深结果,分析研究区深部电性结构特征及主要断裂构造特征,结合地质条件和地热地质资料,对承德机场临空区地热资源进行评价与预测,圈定 2 处地热资源有利靶区.通过对可控源音频大地电磁测深法在该区域的应用,揭示了地下地热构造的分布特征,为承德机场临空区地热资源的开发提供了技术支撑.
Abstract
To explore the geothermal resource conditions in the airport area of Chengde Airport and select the favorable target area,this paper uses six CSAMT profiles to carry out data processing.According to the results,the characteristics of the deep electrical structure and the main fault structure in the study area were analyzed.Combined with the geological conditions and geothermal geological data,the geothermal resources in the airport area of Chengde Airport were evaluated and predicted.The application of the CSAMT method in the area was analyzed and discussed,and the distribution characteristics of underground geothermal structures were revealed,which provided technical support for the development of geothermal resources in the airport area of Chengde.
