摘要
为了对比分析广域电磁法(WFEM)和音频大地电磁法(AMT)的勘探效果,在青海省八宝山页岩气区块已经过钻探工程验证的典型剖面上进行了两种方法的对比试验。结果表明:WFEM相对于AMT具有抗干扰能力强、勘探深度大、深部低阻分辨能力强等优点,AMT相对于WFEM具有工作效率高的优势,但勘探深度较浅。
To compare and analyze the exploration effect of Wide Field Electromagnetic Method(WFEM)and Audio magnetotelluric method(AMT),a comparative test of two methods has been carried out on the typical section of the shale gas block of Babaoshan in Qinghai Province,which has been verified by drilling engineering.The results show that the WFEM has the advantages of strong anti-interference ability,great exploration depth and deep low resistance strong resolution,AMT has the advantage of high working efficiency relative to WFEM,but the exploration depth is shallow.
