摘　　要：胡状集油田已进入以高含水、高采出程度为基本特点的中后期开发阶段,进一步开发的难度加大,因此建立精细的注水开发前后储层流动单元模型有利于掌握储层性质的动态变化,为确定开发方案提供依据。本次研究从取芯井入手,通过参数优选,建立流动单元的判别解释标准,应用聚类和判别分析方法,将流动单元分为3类,并建立流动单元的判别解释模型,对非取芯井进行流动单元判别解释。在此基础上,利用随机模拟的方法进行井间流动单元的预测,建立流动单元的三维预测模型。Huzhuangji oilfield has entered the middle-last development stage with the characteristic of high water containing and high recovery degree, which is difficult for further development. Thus it is important to master the dynamic change of reservoir character to establish fine 3D model of flow unit, which provides the theory for setting up development project. After analyzed the data from coring wells and chose good parameters, we established the standard of differentiated explaining of flow unit and established the differentiated explaining model of flow unit by the methods of cluster analysis and discriminant analysis, then explained the flow unit from coring-free wells. On the basis of above studying, we predicted flow unit among wells by simulation at random, and established 3D predicting model of flow unit.
