The progress of oil reservoir exploration in Cheguai area is slow according to the exploration strategy of fault block reservoirs in recent years. Based on the analysis of sedimentary system and fracture system, the Jurassic in the area is favorable for forming lithologic reservoirs. The result indicated that the high point of palaeohigh is favorable for stratigraphic trap formation, and the combination of sub latitudinal fault, longitudinal sedimentary system and nose- shaped structure turning northwest are good for forming fault- stratigraphic trap and fault - lithologic trap; Badaowan Formation of LST and San′gonghe Formation of HST are the most prospecting formations; delta front below slope break belt is the most favorable area; translocation system is the dominant factor for the forming of Jurassic lithologic reservoirs.
