%X The paper shows the imaging result of Paleozoic sediment stratum in the South Yellow sea.The result shows that there exists relative stable residual Paleozoic sediment stratum in the upheaval zone of South Yellow Sea. Due to the existence of interval multiples and long-way multiples, the seismic imaging is very difficult in residual Paleozoic sediment stratum in the South Yellow Sea. In this paper, the data is transformed to plane-wave domain firstly, and then the prediction deconvolution is applied to attenuate the interval multiples. The velocity difference between the multiples and the effective waves are used to attenuate the long-way multiples. First the multiples with lower velocities and distinguish from the effective waves are seperated, and then seperates the multiples with higher velocities, the imaging velocity and the effective waves are re-determined during the iterative process, until all long-way multiples are attenuated and suitable imaging velocity are obtained. The imaging result is meaningful to the residual basin research.
