复杂断块油田流动单元划分及剩余油分布规律研究

A Study on Flow Unit Model and Distribution of Remaining Oil in Complex Fault Block Reservoir

在掌握储层流动单元概念的基础上,系统总结了目前划分储层流动单元的各种方法。综合运用多学科理论,对我国东部某复杂断块油田应用聚类分析法找到了划分流动单元的有效参数和定量界限,并在该断块整套储层中定量划分出四套流动单元,它们各自具有不同的岩性和储层物性。综合研究流动单元类型与剩余油分布的密切关系,揭示了该断块油田流动单元类型与剩余油分布的关系。

Based on the concept of reservoir flow unit, a series, of methods for recognition, classification and evaluation of flow unit are summarized systematically. By using multi-subject theory comprehensively, cluster analysis is applied in a complex fault block reservoir. Effective parameters and quantitative enclosure are discovered, the complete set of reservoirs are divided into four different kinds of flow unit, which have their own lithologic character and reservoir parameters of property. Combining the study of flow unit with the study of remaining oil closely, the relationship between flow unit and remaining oil distribution of the fault block is revealed.
