[Abstract] There
are various noise in the seismic data.Many methods available nowadays
suppress the effective signal while eliminating some noise.The paper puts
forword a demigration technique which aims at the low S/N ratio shot seismic
recorders.It adopts non-recursion KIRCHHOFF integral method based on ray
theory,which can enhance the effective signal,attenuate the random noise
improve the S/N ratio of seismic data. The results show that the S/N ratio
of shot recorders is increased,the quality of velocity spectrum is improved
and the effect of stacked section is obvious better. [Keywords] Prestack time migration;Demigration;Low S/N ratio.q |
