摘要
储层流动单元的研究可以更好地了解油水运动规律及开发过程中剩余油的分布。基于储层非均质性的层次性,可分步骤建立流动单元模型。该方法利用高分辨率层序地层学分析储层层序内部结构与分隔单元,从沉积单元入手,在建立储层建筑结构和砂体连通性研究的基础上,进行流动单元的划分。研究结果表明,码头庄油田储层流动单元的分布与沉积微相密切相关,应用流动单元空间分布可定性分析其储量动用状况并预测剩余油的分布。
Research on reservoir flow units may better understand the rule of oil-water movement and distribution of remaining oil during the development process. According to the hierarchical properties of the reservoir heterogeneity, the flow unit model can be founded by following steps. In this method high-resolution sequence stratigraphy is used to analyse inner structure and separate u-nit of reservoir sequence. Beginning with sedimentary unit, based on founding reservoir architectural structure and research of sandbody connectivity, flow units are divided. The research shows that the distribution of reservoir flow units in Matouzhuang oilfield has close relationship with sedimentary microfacies, using space distribution of the flow units may analyse its producing reserves status and forecast the distribution of the remaining oil.
