探讨了在电偶源频率电磁测深中利用磁场比值定义的视电阻率ρzy 的物理意义及与其相位间的频散关系,给出了在频散关系的基础上由视电阻率资料估算相位的方法,并证明所估算的相位与理论模型计算值是一致的.研讨了ρzy 与φzy 联合反演问题, 并研制出具有较好应用效果的实用化软件.
The physical meaning of the apparent resistivity ρzy defined by the ratio of the magnetic field and its dispersion relation with the phase in the electromagnetic dipole of the dipole frequency source are discussed. The phase dispersion based on the apparent resistivity data is given Method and proves that the estimated phase is consistent with the calculated value of the theoretical model.The joint inversion of ρzy and φzy is discussed and a practical software with good application effect is developed.
