Abstract：In order to clarify the position of large boundary fault and inner-structure of faulted zone within south steep slope of Miyang depression and starting from the demand of four key processing links (static correction，velocity analysis，3-D DMO and migration)on raw seismic data,the paper designed 3-D seismic geometry. After the balance between various processing demands and work efficiency,the numbers of line in each patch,the length of line for full-fold，bin-size，folds both in in-line and cross-line direction and the pattern of spread are defined. The results of application showed that the quality of seismic data acquired from using abovementioned methods are greatly improved in comparison with the legacy data: distinguished position of fault imaging，reliable feature of events on the targets and above and improvement of resolution and S/N ratio，basically reached the predicted effects.
