摘　　要：辽河油田杜 84块兴隆台油层为超稠油油藏。储层埋藏浅 ,压实程度与胶结程度低且以粘土矿物胶结为主 ,处于早成岩阶段。储层孔隙发育 ,以原生粒间孔为主 ,次为粒间溶孔和裂隙孔。根据铸体图象和压汞曲线获得的孔隙结构特征参数确定 ,该储层孔隙直径大 ,喉道直径中等 ,属大孔中喉道型。因此该储层物性好 ,含油饱和度高 。The Xinglongtai oil layer of Du84 block in liaohe oil fields belongs to Super heary oil pool.The reservoirs which show shallow burial as well as poor compuction and cenmentation stand in the stage of eodigenesis.The cement is mainly clay minerals.The reservoir pore,in which soluted interpartical one and fracture one is the second,is well developed.According to the characteristic parameters of pore textures obtained from the casting images and the capillary pressure curves,the reservoirs for having big pore diameter and throut diameter belong to big pore middle throat type.As a result,the reservoirs which represent well physical property and hing oilbearing sautribitity are chies exploitation fargets in this area.
