CSAMT法以其探测深度大、分辨能力高、设备轻便等特点广泛应用于地下水资源勘查、金属矿产勘查、石油勘查等领域,其中:在地热勘探中,对深大导水导热断裂构造的发现与追踪效果尤为突出,同时对储热构造电性层的分布情况、保温性与含水性判断也较为实际,该方法已成为地热开发论证及地热开发钻孔设计的重要途径之一,几乎已成为地热探勘必备手段。本文介绍了CSAMT法原理、方法及资料处理等方面的内容,最后以CSAMT法在贵州地热资源勘察中的应用为例,例证了该方法在地热勘察中的良好效果。
The CSAMT method is widely used in groundwater resources exploration, metal mineral exploration and petroleum exploration because of its large exploration depth, high resolving power and light equipment. Among them, in geothermal prospecting, the discovery of deep aquifer thermal conductivity fault structures and The tracking effect is particularly prominent. At the same time, it is also practical to judge the distribution of electric layer, thermal insulation property and water-bearing property of thermal storage structure. This method has become one of the important ways of geothermal development demonstration and drilling design in geothermal development, Exploration necessary measures. In this paper, the principles, methods and data processing of CSAMT method are introduced. Finally, the application of CSAMT method in geothermal resource exploration in Guizhou is taken as an example to illustrate the good effect of this method in geothermal prospecting.
