Abstract：Seismic layer-labeling is an effective method for connecting geologic,logging and seismic data.The resently-used layer-labeling methods in practice are variety and there are shortcomings if only using each method alone,therefore,the paper presented integrative layer-labeling method of seismic data based on synthetic seismogram.Its concrete steps are as follows:① building up high precious velocity field;②taking depth-time transform as a basis,determining the corresponding relation of wave-group characters between synthetic seismogram and seismic traces near borehole and labeling the seismic profile with corresponding geologic horizons; 30taking the marked bed and major objective events on seismic sections as a mark,repeated correlation of seismic sequence labeled by single-well is carried out according to the sequence of single-well-to-line-to-plane so that the unified corresponding relations between the sequence and the wave-group characters have been formed at all well sites;④through synthetic analysis,the corresponding relations between lithologic,electric and physical characters on logging curves and seismic traces near borehole as well as other seismic parameters are created.Application of the method to oil-gas exploration and development in Miyang depression has achieved good geologic results.
