摘要
CSAMT法简称可控源音频大地电磁法,采用人工控制场源,信号强度高,具有较强的横向分辨和抗干扰能力。在莘县马西林场地区进行地热资源普查中,CSAMT法能够大致划分第四系、新近系、古近系及热储层的界面,并对断裂构造具有较好的横向分辨效果,可以查清深部隐伏的断裂构造的埋深及展布特征。应用于地热资源地质成矿有利条件的前期普查中,能够取得较好的效果。
Controlled source audio magnetotelluric method is CSAMT method for short.It uses manual con-trol field source with high signal strength.It has strong lateral resolution and noise immunity.In the geo-thermal resources survey in Maxi forest farm area in Shenxian county,profile interfaces of Quaternary, Neogene,Paleogene and thermal reservoirs can be roughly divided by using CSAMT method,and has good lateral resolution effect to faults.It also can verify the depth and distribution characteristics of deep hidden faults.This method has been applied in preliminary geological survey of ore forming favorable conditions and achieved good results.
