高含水油田流动单元定量研究方法--以双河油田为例

介绍了储层流动单元的研统方法，确定了流动单元分类与划分的参数。对双河油田V下油组储层流动单元进行了定量研究。对于取心井，利用岩心的物理分析资料，参照油田开发的实际情况，选择了聚类分析和流动分层指标方法，将其划分为4种流动单元类型，并分析了不同类型流动单元的流动分层指标的分布范围。对于非取心井，利用取心井聚类分析的结果，采用逐步判别分析方法，建立了流动单元类型的判别函数，从而达到了定量研究流动单元类型及其井间分布的目的。生产实践证实，运用这种研究思路划分流动单元的结果与生产实际吻合程度高，说明了这种研究方法是切实可行的。

Quantitative research method of flow units in high- water cut oilfield--taking Shuanghe Oilfield as an example

Research method for flow units of reservoirs was introduced. The parameters of classification and division of the flow unit were determined. The flow units of lower parts of oil group V in Shuanghe Oilfield were researched quantitatively. Clustering analysis and flow zone index method were chosen to classify the flow units of four types for cored wells according to the physical analytical information of the cores and actual development situation of oilfield. Distribution range of flow zone index for various types of the flow units was analyzed. For the non - cored wells,the method of discriminant analysis step by step was adopted to establish the discriminant function of different types of flow units according to the results of clustering analysis of the cored wells. So the goal of quantitative research on the flow unit types and their inter - well distribution was a-chieved. Production practice proved that the results of flow u-nit classification got by this research thought tallied with practice well. That is to say, the research way is feasible.
