可控源音频大地电磁测深在地热资源中的应用

Application of Controlled Source Audio Magnetotelluric(CSAMT) in Geothermal Resources

可控源音频大地电磁测深(CSAMT)是在大地电磁测深法(MT)的基础上发展起来的一种人工源电磁测深法。国内一些单位采用可控源音频大地电磁测深法在探寻地热及地下水资源等方面做了大量工作,取得了良好的实际应用效果。在某温泉旅游区进行了物探方法,通过卡尼亚视电阻率共轭梯度反演断面异常为例进行分析解释,探讨了可控源音频大地电磁测深法在地热地球物理勘查中的应用效果。

Controlled source audio magnetotelluric （CSAMT） is an artificial source electromagnetic sounding method developed on the basis of magnetotelluric sounding （MT）. In China, there are much research on the application of controlled source audio magnetotelluric （CSAMT） in the search for geothermal and groundwater resources, and has achieved positive result. We conduct geophysical prospecting at spa tourism area, taking Carney ATV conjugate gradient inversion of resistivity anomaly as example, analyzes the application effect of controlled source audio magnetotelluric sounding method in geophysical exploration of geothermal.
