高集油田目前已进入高含水后期开采阶段，受沉积环境、成岩作用和构造因素的综合影响，储层非均质性强，井间和层间矛盾突出，储层流动单元研究应从多方面考虑。通过主因子分析优选出符合工区实际的5个地层参数作为主控参数，采用综合聚类分析方法，对目的层阜宁组一段的流动单元进行研究，将阜宁组一段储层划分为4类流动单元。在流动单元划分及分类评价的基础上建立研究区流动单元三维地质模型，总结流动单元分布规律。分析流动单元与剩余油分布关系，指出Ⅱ、Ⅲ类流动单元分布区具有较好的剩余油开发潜力。

At present Gaoji Oilfield entered into the late stage of development with high water cut.A combination of depositional environment,diagenesis and structural factor contributes to higher heterogeneity of reservoir and bigger inter-well and interlayer interference.Therefore,the flow unit of the reservoir was studied from many different perspectives.By principal factor analysis,five formation parameters,which agree with actual values in the study area,were optimized as main control parameters.By using the cluster analysis,the reservoir in the first member of Funing Formation in target stra-tum was divided into four types of flow unit.On the base of division and classified evaluation of the flow unit,a 3D geolog-ical model of the flow unit was established in the study area.And distribution rules of the flow unit were summarized.By analyzing the relationship between the flow unit and remaining oil distribution,typeⅠand typeⅡof flow units are good po-tential for the remaining oil development.
