HACSAMT法在地热勘探中的应用研究

HACSAMT Method and its Applicatian in Geothermal Exploration

谐波可控源音频大地电磁测深(HACSAMT)方法是地球物理勘探方法中重要方法之一。它采集其高次谐波的振幅和相位的数据,加密CSAMT法勘探的频率,提高了纵向分辨率。本文以地热勘探为实例,采用GDP-32多功能电法仪进行数据采集处理,利用HACSAMT法查明研究区多个断裂构造的空间发展分布规律,从而确定了地下热水的存储部位。

Harmonic controlled source audio-frequency magnetote-llurics method, usually called HACSAMT,is one of most important methods in the geophysical prospecting methods. It collects the amplitude of the high hypo humorous and the data of the phase to encrypts the frequency of CSAMT method reconnoissance and improves the vertical resolution, while observing first wave.The paper taked example for geothermal exploration,and used GDP-32 to data acquisition and process, making use of HACSAMT method to find out the rule of faulted structure and to detemine the keystone.
