摘要: 针对克拉玛依油田二中西区八道湾组砾岩油藏高含水开发期的特点,提出了砾岩油藏流动单元定量划分方法。通过对取心井参数优选,采用聚类分析的方法将储集层流动单元划分为4 种类型,建立了各类流动单元的数学判别函数进行判别分析,对非取心井进行了流动单元划分,并应用序贯指示模拟方法建立了流动单元三维地质模型,更加准确地反映了地下流体的流动特征,为预测剩余油分布规律、油田后期开发调整及提高采收率提供了重要的地质依据。

Abstract: Based on the keystone of flow unit, a quantitative classification method is proposed for conglomerate reservoir with high water cut of Badaowan formation in Midwest of District 2 in Karamay oilfield. After optimizing the parameters from cored holes, the reservoir flow units are classified into four types using cluster analysis and the discriminant functions for each type of flow units are set up for discriminant analysis and classifying the flow units of non-cored holes. The flow unit 3D geologic model is developed using sequential indication simulation method, in order to more properly reflect the flowing characteristics of in-situ fluids. This model could be as a guide for forecasting the distribution of remained crude oil, modification of this high water-cut oilfield development and enhancing the oil recovery in this area.

Key words: conglomerate reservoir, flow unit, cluster analysis, remaining oil, Karamay oilfield
