3D wave equation prestack depth migration (PS-DM) is an effective tool for imaging complicated geological structure. However, its successful applications to seismic data, especially land seismic data, are quite few. On a mainframe parallel computer (made in China) we processed field data acquired on the transitional area between the land and tide zone and got excellent image. Our work demonstrates that the wave equation PSDM is of powerful effectiveness for imaging the complex media.
