摘　　要：东营凹陷北部陡坡带利津地区砂砾岩体是早第三纪沙四段时期形成的以砂、砾岩为主的近岸水下扇沉积体。储集层岩石结构成熟度和成分成熟度均较低,多为双模态和复模态结构。首先对影响储集层物性的主要成岩作用进行了描述,分析了该砾岩体储集层的孔隙类型和孔隙结构特征。该类砂砾岩体储集层孔隙类型多样,孔隙结构复杂,以中 低孔隙度、低渗透率储层类型为主。Sandstone and conglomerate body in Lijin area in north slope of Dongying depression is a nearshore subaqueous fan reservoir which is the forth member of Shahejie formation Sand and conglomerate are the main rock types The reservoir is of the lithological characteristics of low composition and structure maturity,and bimodal or polymodal structure Firstly this paper describes the diagenesis influencing the performance of reservoir Then pore types and feature of pore structure are analyzed The reservoir of sandstone and conglomerate body in Linjin area possesses sorts of pore types,complex pore structure,middle low porosity and low permeability

关 键 词：利津地区 砂砾岩体 成岩作用 孔隙结构 低渗透储集层 东营凹陷 早第三纪 成熟度
