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 technology 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.
