摘要
CSAMT(可控源音频大地电磁测深)方法以其探测深度大、分辨能力高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,可取得常规电法所无法比拟的勘查效果,尤其适用于圈定地下水资源的空间赋存位置、规模、属性、连通性等钻前勘查工作;近年来我院在全国各地所承担的地下水及地热勘查工作,采用CSAMT方法均取得了良好的应用效果;本文从方法的原理特点出发,总结了该方法应用于地热勘查的主导思想及所需注意的问题,最后给出了部分实例以资借鉴。
CSAMT is a geophysical technique characterized by large depth detection and high resolution thus widely used in exploration of underground water, metal mineral resources and petrolium with incomparable results. Especially, it is superior in determining spatial locality, size, property and connection of underground water before drilling. Based on experiences of geothermal exploration projects undertaken in recent years this paper introduces the working principle and key points and problems to which more atten-tion should be paid during geothermal exploration.
