综合物探方法在江西临川温泉勘查中的应用

Application of Integrated Geophysical Exploration on Hot Spring in Linchuan

温泉是出露地表的地下热水,临川温泉的出露明显地受断层破碎带的控制,温泉为中低温水热系统。大量资料表明,地球物理方法是地下热水勘探不可缺少的手段之一,为了进一步扩大临川温泉资源的开发利用,在临川温泉区开展了地球物理勘探(磁法、氡气测量、地噪声观测、电测深)工作。通过各种物探工作,阐述了温泉与地球物理场的内在联系,圈定了控制热水的断层破碎带。根据综合物探方法推断成果,钻探出了地下热水。

Hot springs are geothermal water emerging on the ground surface. The outcrop of thermal springs, hydrothermal resources with low to moderate temperature, is obviously controlled with the fault-fractured zones in Linchuan area. Mass of local data show that geophysical exploration techniques are indispensable means in geothermal water exploration In order to improve the utilization of hot-spring resources, these techniques, such as resistivity sounding, magnetic survey, radon gas survey and earth-noise measurement, have been applie on Linchuan area. As a result, approach to locate fault-fractured zone which controls the distribution of geothermal water and the intrinsic relationship between thermal springs and geophysical field, have been described in this paper in details. Based on the integrative geophysical surveys, an inference was made and thermal water had been located through drilling.
