Abstract

Cross-well seismic has the characteristic of high resolution. It can solve the exploration problems of stratigraphic trap and lithological trap in small scale and complex structure. In order to solve the problems of cross-well seismic wave imaging effectively, the paper uses Gauss beam forward method to obtain the velocity field and reflection points in complex structure; The common reflection point gathers are gotten by using the idea of inverse Gaussian beam to migrate the reflection wave field to the correct position; Then the imaging field characteristics can be acquired through stacking data in an appropriate bin size. A large number of model tests show that, the inverse Gaussian beam stack imaging method of cross-well seismic can effectively inverse the underground structure. The method is used in the cross-well seismic imaging of K area, the results show that this method could accurately and rapidly image the underground complex and small scale structure characteristics, and provide the basis for further seismic data processing.
