绥靖油田G14区延911藏流动单元研究

Research on flow units of Yan 9_1 reservoir in G14 district of Suijing Oilfield

针对之前一些流动单元的划分方法的不实用等问题,应用了以孔隙度、渗透率、含油饱和度、泥质含量四个参数为划分依据的多参数聚类分析划分流动单元的方法。分别用判别分析回判和动态生产数据的方式对延911小层流动单元划分结果进行验证。结果表明此方法能够很好地满足油田单位的生产要求,有利于油田开发规划和采收率的提高。

In view of the practical problems of the method of dividing the flow units,the authors applied the method of multiparameter clustering analysis based on porosity,permeability,oil saturation,and mud content of four parameters.The results areverified by using discriminant analysis and dynamic production data to verify the results of 911 small layer flow units.The results showthat this method can meet the requirements of oil field unit,and it can improve the oil field development plan and oil recovery.
