Abstract: Due to the lack of original seismic data covering the area of Weixi wellsite, two volumes of 3D seismic data previously acquired in different direction were processed with conventional processing technology to get the high-resolution seismic data for the prediction of shallow geological hazards. Comparing with the conventional high-resolution processing of seismic data near wellsite, the main difficulties involved in this paper are as follows:(1) inconsistency of the acquisition grid; (2) matching problem; (3) removal of the multiple; (4) improvement of the resolution; (5) selection of the migration method. In this paper, the solutions have been proposed after analyzing the problems mentioned above. It shows that the methods can meet the requirements for the interpretation of seismic data could supply high quality data for seismic data interpretation, and the experience will be helpful to dealing with the similar problems later. In the meanwhile, the author also proposes some suggestions to improve the acquisition of data in the future.
