Abstract：In view of the problems existed in traditional formula computing bin size and folds, the paper redefined the conception of bin and presented new computation formula, making the computation formula have wider usage scope. According to new computation formula, the feature of geometry can be better analyzed in combination with the analysis of crossline geometry: on the one hand, the seismic resolution can be improved by fine-sorted bin size, and on the other hand, the super-bin array processing can be carried out based on processing, which can improve S/N ratio of seismic data in combination with pre-array processing of denoise and static corrections. Doing so can both present new idea of design of seismic geometry and play the superiority of flexibly designing bins in the design of seismic field acquisition.
