可控源音频大地电磁法在地热探测中的应用

Application of controlled source audio geomagnetic method in geothermal exploration

地热作为清洁能源,广泛应用于取暖、洗浴、旅游等多种领域。地热探测最终勘探目的是寻找热储构造,即断裂构造破碎带。地热的勘查方法有很多,可控源音频大地电磁法为其中一种较为经济适用的方法。相对于其他方法,可控源音频大地电磁法具有勘探深度大、工作效率高、分辨率高等优点,通过对吉林磐石地区的项目工作研究,证明了可控源音频大地电磁法在地热探测中的良好效果。

Geothermal as a clean energy source has been paid more and more attention and developed in recent years,and is widely used in various fields such as heating,bathing and tourism.The ultimate exploration purpose of geothermal exploration is to find thermal storage structures,i.e.,fracture-tectonic fracture zones.There are many methods of geothermal exploration,and the controlled-source audio geomagnetic method is one of the more economical and applicable methods.Compared with other methods,the controlled-source audio geomagnetic method has the advantages of large exploration depth,high efficiency and high resolution,and the good effect of the controlled-source audio geomagnetic method in geothermal exploration was proved by the project work in Jilin Panshi area.
