The effect of medium of the earth at different positions to the measurement of frequency electromagnetic sounding with dipole-dipole array is analysed. It is pointed out that when frequency sounding profiling is carried out under the complex geological condition, parallel dipole array with the current electrodes fixed and the potential electrodes moving along the profile is appropriate, and the data should be recorded at the middle point of the potential electrodes.

The effect of medium of the earth at different positions to the measurement of frequency electromagnetic sounding with dipole-dipole array is analysed. It is pointed out that when frequency sounding profiling is carried out under the complex geological condition, parallel dipole array with the current electrodes fixed and the potential electrodes moving along the profile is appropriate, and the data should be recorded at the middle point of the potential electrodes. Relatively large current electrode spacing may be used to get strong signal and small potential electrode spacing may be adopted to acheive high resolution. The array coefficient expression for parallel dipole array with large current electrode spacing is derived.

分析了大地中不同位置的介质电性对赤道偶极装置频率电磁测深结果的影响,指出在复杂地质条件下作剖面性频率电磁测深,宜采用固定供电电极位置,只移动测量电极的平行电极装置,将测量电极中点定为纪录点;采用较大的供电极距以获得较强的测量信号和较小的测量极距以获得较高的横向分辨率。推导了有限长供电极距的平行电极装置的装置系数公式。

Analyzing reasons for system errors in measurement of earth resistivity, several methods to remove the errors are proposed.
