Abstract：Seismic horizons labeling is basis of structural interpretation of seismic data and study of seismic reservoir. There are many factors that affect the precise of horizons labeling. In order to eliminate the influence of time-distance relationship on seismic synthetic records,we suggest using time-scanning method to replace manual-shifting method. The time-scanning method can also be divided into integral-time-scanning method and local-time-scanning method. In order to eliminate the influence of the characters of used wavelet phases, we suggest using phase-scanning method to select optimum matched wavelet to make synthetic records on the basis of using time-scanning method to accurately determine the time-distance relationship,which can realize optimum seismic-horizons labeling.
