英文摘要	Because of rugged seafloor, complex underground structure, and well developed multiple waves in 2D seismic data in southern South China Sea, it is difficult to obtain satisfactory imaging results in seismic data processing. This paper attenuated the multiple waves effectively, enhanced the effective signal energy by using a combination solution of filtering in F-K domain after predictive deconvolution and the Radon transformation after pre-stack time migration to remove multiple waves. We achieved accurate imaging of steep angle structures and seamounts, by increasing velocity point densities to analyze more accurate velocities. The clear seismic imaging was obtained by using percentage scanning curved-ray Kirchhoff pre-stack time migration method, to effectively ensure the accuracy and validity of the results. Eventually a processing flow was formed for seismic data in the southern South China Sea.
