| 摘 要： | 低渗透油田开发在中国石油工业中具有特别重要的意义。应用岩心、测井等资料将山东五号桩油田桩74块远岸浊积扇划分为扇根、扇中、扇缘3个亚相,其中扇中亚相划分为辫状水道、水道间、水道侧缘、扇中前缘及叶状体5个微相类型;阐明了研究区特低渗透油藏内储层的层内、层间及平面非均质特征;系统总结了微构造的类型及组合模式。在沉积微相、储层非均质性及微构造研究的基础上,采用动态、静态结合的分析方法阐明了研究区特低渗透油藏的剩余油分布规律及控制因素,揭示了沉积微相、储层非均质、微构造及井网条件等因素对剩余油分布的控制作用。根据剩余油分布的研究结果,结合相关资料,指出了剩余油潜力区,有针对性地确定了剩余油的挖潜措施,为增加剩余可采储量和提高采收率提供了科学依据。 |

| Abstract: | The development of extra-low permeability reservoir plays an important role in oil industry. Based on core and well logging data, the distal turbidite fan of Block Zhuang74 in Wuhaozhuang Oilfield can be divided into three subfacies, that is, root fan, middle fan and fan edge. In middle fan, five microfacies can be recognized such as braided channel, inter-channel, channel edge, front edge of middle fan and lobe. Internal, interlayer and plane heterogeneities are clarified, then the types and combined modes of micro-tectonics are summarized. On the basis of the analyses of dynamic and static data, the distribution and controlling factors of the remaining oil in extra-low permeability reservoir are revealed, including microfacies, reservoir heterogeneity, micro-tectonics and well network condition and so on. The enrichment regions of the remaining oil are predicted and potential exploitation measures are proposed, then the increments of remaining accessible reserves and the enhancement of recovery can be achieved. |
