Contrastive Analysis of Georesistivity in Deep-well and on Ground at Dabaishe Station

This article introduces the georesistivity observation in deep-well and that on ground at Dabaishe Station in Heibei province, analyzes the accuracy, anti-interference ability and the law of annual variation etc. The analysis shows that the observation accuracy and anti-interference ability observed in the deep-well are better than that of the ground observation, and furthermore the annual vibration of the georesisitivity observed on ground is remarkable, while that of the georesistivity observed at the deep-well is not.
