摘　　要：渤中凹陷古近系是目前勘探和研究程度相对较低的层位。该地区大面积分布碎屑岩储集体,沉积体系多样化,岩石类型以长石砂岩、岩屑长石砂岩、长石岩屑砂岩为主,储集性能较好,孔隙度较高,储层物性主要受岩石类型、沉积相带、成岩作用,以及埋藏深度等多方面的因素控制。The Palaeogene reservoir rocks in central Bohai Gulf depression are believed to be less developed in the current aspects of research and exploration. The clastic reservoir rocks occur on a wide range of scales in varying depositional systems in the depression. The rock types are composed of arkose, lithic arkose and feldspathic litharenite with good reservoir quality and high porosity. The physical properties of the reservoir rocks primarily depend on the rock types, sedimentary facies, diagenesis and burial depth.
