This article put forward an attribute model for 5\|unit group soft structure,discussed the related method and languages,and described this model by example of BNF.

To obtain more accurate structural buried depth in seismic exploration, methods are proposed ior establishing an attribute model velocity field, the formation unit that has great influence on its velocity is considered comprehensively in the methods geologic, petrophysic and compaction data are used to build a velocity model more accurately and objectively in combination with seismic data.
