The research results indicate that the qualities of the Jurassic reservoir are dominated by construction. Good reservoirs lie to an advantaged nose protrusion, nearly relating to the distribution of sedimentary micro-facies. The reservoir that lies on the main position in the riverway has better gathering characters. Because argillaceous content is increase and the porosity and permeability became smaller, the character of the reservoir becomes bad in the flood plain area that lies on the skirted riverway and between riverways. Characters of the layer relate to the distribution of main sand-body that the better feature of the layer and the bigger thick of sandbody layer.
