| Abstract: | Because of the low SNR and bad interference by multi-wave in the original 3d seismic data,many modules are used to suppress and wipe off the multi-waves and to increase SNR at whole course of data processing.The method of the modeling radial trail is used to obtain accurate excursion velocity space to make 3D one-step excursion.The preponderant frequency deconvolution is used to increase the resolution ratio. |

| Keywords: | whole course multi-wave FK-filtering modeling velocity space preponderant frequency deconvolution |
