There are maily litharenite and feldsparthic litharenite, which are middle diagenesis stage,The reservoir physical properties have relationship with depositional facies and petrographic facies.the shore reservoirs are the best ,and the reservoirs of braid and stream delta are better than the reservoirs of fan delta .The braid delta plain reservoirs are better than braid front reservoirs,and the fan delta front reservoirs are better than the fan plain reservoirs.The palaeo depth and late cements are the main factors controlling the reservoir physical properties. There are two stages dissolution which improve the reservoir physical properties .Intense extrusion has also effect on the reservoir physicalproperties .
