摘　　要：基于聚类分析法、岩石参数法等多种方法,对长庆油田不同类型油藏流动单元进行研究,从而筛选出适合长庆油田不同类型油藏流动单元划分的主要方法、主要参数和针对油藏自身特征的特殊参数,并将各参数定量或定性化。结果表明,适合长庆油田低渗透储层流动单元划分的主要方法有聚类分析法和多参数综合法两种;参数选取应同时考虑常规基本参数和油藏自身特征的特殊参数;各类油藏流动单元可划分为4种类型。By analyzing different flow units in Changqing Oilfield, using cluster analysis method, and Litholo- gy characteristics method, etc. This study screened out the main classification methods, as well as the key pa- rameters, and specific parameters for reservoir in Changqing Oilfield, and all the parameters have been quali- tatived and quantitatived. The result showed that there were two classification methods suitable for flow units in low permeability reservoir in Changqing Oilfield. Considering the regular basic parameters and reservoir specif- ic characteristics when selecting parameters. The flow units in Changqing Oilfield, the main production series can be classified into four types.
