With the increasing difficulty of exploration and oil development, the broadband seismic has gotten more attention. At present slant streamer is generally considered one of the most popular methods to obtain broadband seismic data. In this paper, the key technologies of broadband processing are studied according to the characteristics of slant streamer. These key technologies are deghosting method based on wave equation iterative inversion, streamer depth correction method based on wavefield extrapolation and Q compensation on broadband data. The application of these methods on real seismic data shows that the ghost of slant streamer data can be effectively removed by wave equation iterative inversion. The accuracy of streamer depth correction can be improved by wavefield extrapolation. The middle-deep resolution and wide band of seismic can be recovered by Q compensation.
