摘　　要：对盘古梁长6油藏某区块进行了精细分层对比和沉积特征研究,采用基于Kozeny-Cayman方程的定量方法,选取储层质量指数、标准化孔隙度、流动带指数、孔隙度、渗透率等反映岩石物性的5个参数,利用SPSS13.0数学统计分析软件进行聚类分析,将流动单元分为A、B、C 3类,得到了流动单元的分类特征和分布规律,并通过初期产液量来验证.表明此次流动单元的划分能够真实客观地反映该地区低孔、特低渗的地质特征和渗流特征.应用此方法对特低渗透储层流动单元评价划分是合理的,可以用来指导油田进一步开发调整,以及为提高采收率提供重要的地质依据.The studies on reservoir flow units should be closely combined with oilfield development.Based on the fine stratification comparison and the study of sedimentary characteristics of a block of Chang 6 in Panguliang,the flow units of the block are classified into three typed of A,B and C.In the classification of reservoir flow units,reservoir quality index(RQI),standardization porosity(φz),fault zone index(FZI),porosity,permeability being taken as cluster parameters,the cluster analysis of them is carried out using the quantitative analysis method based on Kozeny-Cayman equation and SPSS13.0 statistical analysis software.The classification characteristics and the distribution rule of the flow units are obtained.The classification result is verified by initial liquid production.It is shown that this division of flow units objectively reflects the geological characteristics of this block,such as low porosity,extremely low permeability,and also reflects the characteristics of the seepage flow capacity of the block.The division result of flow units can be used for guiding the further oilfield development,and can offer the important geological basic data for enhancing oil recovery factor.
