THE STATIC DISPLACEMENT AND THE DISTORTION OF APPARENT RESISTIVITY CURVES BY FEMS

摘要:

以电偶源频率电磁测深(FEMS)二维数字模拟为例,从理论上简略讨论了波区定义的5种视电阻率的变化特征及静位移现象,定性分析了表面局部水平非均匀体对视电阻率曲线畸变的影响.

Abstract:

Based on two dimensional digital simulation of the frequency electromagnetic sounding with electric dipole supply,the variation characters and static displacement of five kinds of apparent resistivity in wave area are theoretically studied,and the effects of surface local lateral inhomogeneities on distortion of apparent resistivity curves are qualitatively analysed.
