摘　　要：裂缝性低渗透岩性油藏物性复杂,控制因素多样,开采难度大,寻找储层物性的主控因素是该类油藏有效开发的基础。以大情字井油田黑43块为例,在对青山口组青一段储层沉积相、岩性特征、裂缝方向、低幅度构造综合评价基础上,分析了低渗透裂缝性油藏储集特征,探讨了储层性质对单井产能的影响。分析认为,黑43区块低渗透储层物性主要受沉积相和裂缝控制,剩余储量分布与构造幅度、油藏内的油水分异差别、储集层岩性变化密切相关,为裂缝性低渗透油藏有效开发提供参考。The reservoir physical property of fractured low permeabilitydithologic reservoir is complex, and the promi nent controlling factors are difficult to identify.On the base of evaluating the comprehensive evaluation of lithology characteristics, sedimentary facies, fractures directions and low amplitude structures of Qing I member, Qingshankou ＂Formation,this paper analyzed the characteristics of fractured low permeability reservoir and the effect of reservoir properties on sigle well productivity on the case study of Hei 43 Block of Daqingzijing Oilfield. Tile results show that sedimentary facies and fractures are the main controlling factors of the physical properties of the low permeability reservoir. In addition, the distribution of remaining reserves is mainly dominated by the low structure qmplitude, the reservoir oil-water differentiation and the lithology variations. Thus, this study provided practical significance for the effective exploitation of fractured low permeability reservoir.
