Abstract: Three?component seismic exploration is an effective method for the utilization of P?wave and converted?wave to detect fine structures.With this method,converted?wave imaging profiles have high resolution,and small geological structures such as small faults and small structures can be identified.In this paper,based on the application experiments of three?component seismic exploration tech?nology in Qiangtang basin of Tibet,the authors investigated the three?component seismic data acquisition method,converted?wave data processing technology and comparative interpretation method,and the results achieved prove the effectiveness of this method.This paper has certain reference value for the application and study of multi?component seismic exploration technology in plateau permafrost area in the future.
