The research on 3D prestack depth migration of wave equation has become the focus of many oil and gas exploration and research units at home and abroad in recent years. One of the key issues is the improvement of hardware and software and their matching to solve the huge computational burden. In this paper, starting from the actual oil field, this paper presents a set of three-dimensional prestack depth migration method and processing flow of symplectic geometry algorithm for parallel wave equation. By using 32-node cluster parallel machine, the two-dimensional and WJT Prestack Depth Migration Processing for Waves of 3D Seismic Data in 1226km2 Area. The imaging results have achieved significant improvements in signal-to-noise ratio, resolution, deep complex structure imaging
