The Influencing Factor Analysis of Passive Source SLF Electromagnetic Exploration Experiments at Two Geothermal Wells
Two terrestrial heat wells were explored by using passive source SLF electromagnetic explorer. The influencing factors that involve sensor orientation, 50Hz working frequency and its harmonics, exploring time and weather were analyzed. The results include: the rule of time-dependent variation of nature source and artificial source electromagnetic field signals, the compensation of time variable signals, the coupling between weather and nature source electromagnetic field, the explorer respondence to artificial source electromagnetic field with respect to different orientation of sensor. By contrasting and analyzing the experiment results of two wells, the interference was found and the SNR were therefore to be improved.
