摘要
为了比较广域电磁法(WFEM)和大地电磁法(MT)的勘探效果,在中国南方某页岩气区块进行了对比试验。结果表明,WFEM相对MT具有工作效率高、抗干扰能力强、分辨率高以及地形适应性好等优点,但MT相对WFEM具有探测深度大这一不可比拟的优势。
A comparative test was carried out to compare the exploration effect of the wide field electromagnetic method(WFEM) with that of the MT at a shale gas block in the South China. The result shows that the WFEM has the advantages of high working efficiency, strong anti- interference ability, high resolution and good terrain adaptability, but the incomparable superiority the MT has is that the exploration depth of the MT is deeper than that of the WFEM.
