大地电磁测深法在地热勘探开发中的应用

Application of Magnetotelluric Sounding in Geothermal Exploration and Development

张家口西北部断裂发育,地热资源丰富,由于该区域内未有地热资源的地质资料积累,为查明研究区域地层结构、断裂特征、热储类型等地质条件,对张家口西北部某地的地热资源采用大地电磁测探法进行可行性勘查,基本查明研究区域地层结构、热储层埋深等,为圈定有利地热勘查开发有利区块提供依据。

The northwest of Zhangjiakou has developed faults and is rich in geothermal resources.Since there is no geological data accumulation of geothermal resources in this area,in order to find out the geological conditions of the study area,such as the stratigraphic structure,fault characteristics,and thermal reservoir type,the feasibility survey of geothermal resources in a place in the northwest of Zhangjiakou was carried out using the large area electromagnetic prospecting method,and the stratigraphic structure and buried depth of the thermal reservoir in the study area were basically found out.It provides a basis for delineating favorable geothermal exploration and development blocks.
