Test Analysis on Geoelectrical Resistivity Observation Combining the Surface and Deep-well Methods at Tianshui Seismic Station in Gansu Province

KAN Yun-sheng1,AN Hai-jing2,MA Ke-xing1,TAN Da-cheng1,2(1.Earthquake Administration of Gansu Province,Lanzhou,Gansu 730000,China; 2.Lanzhou National Observatory of Geophysics,Lanzhou,Gansu 730000,China)  
In early 2011,Tianshui seismic station of Gansu province developed a special project for observation on deep-well geoelectrical resistivity,which pushed the horizontal geoelectrical observation to stereo observation.The methods include surface horizontal observation,deep-well horizontal observation,and the electrode interchange-able test between surface and deep-well observation.Through continuous observation in past two years,data obtained by two methods which are deep-well M、N observation supplied power by surface A、B and deep-well horizontal observation is relatively stable and reliable.Meanwhile,deep-well M 、N observation supplied power by surface A、B could contribute to reliability analysis on data changes.At observation sites where electromagnetic environment is more complex,deep-well M、N observation supplied power by surface A、B and deep-well horizontal observation may be two effective methods.
