| 摘要: |
| 流动单元的研究,其目的在于对油藏的非均质性有进一步的认识,为提高油藏描述的精度提供依据。本文根据流动单元的理论,选取适合该区实际的参数,应用聚类判别分析的方法,对华池油田陇东地区长33低渗储层进行分类研究,并且分析各类流动单元的特征及其控制因素,得出结论:该区储层可分为三类流动单元,各类流动单元的判别公式,不同的类型在动态、静态上有不同的表现;其分布的差异,宏观上受沉积微相的控制,微观上受成岩作用、岩石自身储集空间特征的限制。 |

| Abstract: |
| The present paper is designed to improve our understanding of the heterogeneity of oil reservoirs and provide the basis for improving the precision of the reservoir description,with emphasis on the division and controls on the flow units in the Chang-33 oil reservoirs in the Huachi Oil Field,Shaanxi.Three types of flow units may be recognized for the studied oil reservoirs, which are macroscopically controlled by sedimentary microfacies,and microscopically by diagenesis and reservoir spaces. |
