Seismic imaging under the irregular deep water bottom
深水崎岖海底地震数据成像方法与应用

This research aims at attacking the difficulty to image with the seismic data from the irregular deep water bottom. The basic theory of the true amplitude common-shot prestack wave equation migration is discussed. Numerical experiments demonstrate the robustness of amplitude preserving characteristics with true amplitude prestack wave equation migration. This method can increase the resolution of imaging in complex media, in contrast to non-true amplitude migration, demonstrating its effectiveness. Using real data from a seismic exploration, the method is tested with an attempt to handle the difficulty of making images in the irregular deep water bottom, and it is proved that the true amplitude migration can remove the imaging artifacts caused by irregular deep water bottom.
