Seismic imaging under the irregular deep water bottom

CHANG Xu~1, LIU Yi-Ke~1, DU Xiang-Dong~2, LI Xu-Xuan~21 Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China2 CNOOC Research Center, Beijing 100027, China  
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.
