Abstract：At present,the oilfields at home preserved a plenty of seismic paper profile and tape and did not build poststack seismic database,so that can not fully play the role of former legacy data.Using image processing technique,the paper got grating image after scanning the seismic paper profile,that has been transformed into vector data after digital processing,such as binary number representation, geometric correction,removing time axis and seismic waveform searching and detecting,and then these data were transformed into standard SEG-Y format,the further processing and interpretation can be carried out according to present seismic data processing techniques.It can be seen from digital processing of former seismic paper profile that the resulted digital seismic data can restore original face of old seismic paper profile,having ideal effects and providing a feasible way for further processing and interpretation of seismic data that have not been built up the poststack seismic database.Because the legacy data have not been carried out the amplitude hi-fi processing,so post-digital processed seismic data only can be suitable for geologis structural interpretation.
