综合地球物理方法在阜新市四合地区地热资源普查中的应用

The Application of the Integrated Geophysical Exploration to Geothermal Resource Survey in Sihe Area of Fuxin City

阜新市四合地区是地热资源勘查开发的空白区,为查明其地热资源赋存状况,采用了综合地球物理方法(重力勘探、磁力勘探、可控源音频大地电磁测深、大地电场岩性探测),推断了断裂构造位置、热储层顶板埋深及温度范围,确定了工作区南部为勘探靶区,设计了勘探井位,为下一步钻探工作的开展,提供了重要依据。

The Sihe area of Fuxin city is a blank area to develop the geothermal resources. The fault location, depth of the heat stratum layer roof and its temperature are inferred by the integral geophysical survey （include gravity exploration, magnetic exploration, CSAMT and geoelectric field lithology detection） to identify the geothermal resources. As a result, the the exploration target area is determined and the location of drilling well is designed. It provides important basis for the next step of drilling work.
