The Jurassic system in Hashan area is under the tectonic setting of basin-marginal slope, and the complex contact relationship of strata and difficulties in determining the type and effectiveness of traps restricted prospecting courses of this area. According to the outcrop, drilling, seismic and analysis data, the Jurassic system can be divided into 4 third order sequences and 10 system tracts, and sequence stratigraphy framework is established. Through research on sand bodies within the sequence framework we find that Hashan area mainly developed sandbody of humid fans, braided fluvial, meandering fluvial, delta and lacustrine facies, make clear that three types of sandbody stacking patterns are overlap type in LST, isolation type in TST and dissecting-stacking type in HST, and established system tract controlling trap models of 4 classes in 2 types. The unconformity structural characteristics and system tract controlling sand body model coupling controlled the types and development rules of traps in different sequences, that is, carpet sand bodies in LST mainly developed structural-stratigraphic traps, while sandbody in TST and HST developed stratigraphic- lithologic traps.
