| Abstract: | It is the central link of seismic data processing that obtains the seismic relfection proifle deviation with shallow seismic relfection method. In this paper, the authors established needed stratum and velocity models according to different requirements, composed stacked transmitting and receiving proifle for the excursion processing. The proifles were treated with 15° and 45° ifnite-difference method, Stolt method, and phase shift method, the results of treatment were compared, and the difference between algorithms were summarized. |
