高密度电法具有点距小,采集数据量大,采集效率高,探测精度高和探测深度大等优点,在工程地质和水文地质勘查中广泛应用。该次物探工作将高密度电法应用于某工区的地热勘察中,验证了高密度电法在地热勘探中的可行性。采用温纳装置采集的视电阻率数据,经过软件反演后的视电阻率异常特征和断面清晰地反映出裂隙地下延展分布、地下埋深情况,取得了很好的地质效果,为地热勘探提供了地球物理依据。
The high-density electric method is widely used in engineering geology and hydrogeology exploration because of its advantages of small spot distance, large amount of collected data, high collection efficiency, high detection accuracy and large detection depth. The geophysical prospecting work applied the high-density electric method to geothermal exploration in a certain area, and verified the feasibility of high-density electric method in geothermal exploration. The apparent resistivity data collected by the WENER device shows the apparent resistivity anomaly characteristic and section after the software inversion clearly shows the underground fracture distribution and underground depth, and has achieved good geological effects, providing geothermal prospecting Geophysical basis.
