摘要

摘要: 为了揭示扶余油田扶杨油层砂体分布和流体渗流规律,采用层次分析方法,将扶余油层划分成复合河道、单河道、河道内加积体等构型要素,将杨大城子油层划分成河道、点坝、点坝内侧积体等构型要素,并归纳总结了不同构型界面同渗流屏障关系。在此基础上,综合孔隙度、渗透率、流动分层指标(FZI)、剩余油饱和度、水驱指数等参数,采用聚类方法,将扶杨油层划分成4类流动单元,并得到各自的判别标准。结合储层构型,识别出5种流动单元成因类型。油田动态数据和划分流动单元关系表明,流动单元能够有效预测产能、指示剩余油分布和砂体动用效果。

Abstract: Aiming at revealing the distribution of sandbody and the rule of fluid flowing in the Fuyu-Yangdachengzi Formation of the Fuyu Oilfield, the Fuyu Formation was divided into compound channel, single channel and accretion, and the Yangdachengzi Formation was divided into single channel, point bar and lateral accretion through hierarchical analysis. The relationship between architecture surfaces and flow barriers was summarized. Based on parameters such as porosity, permeability, FZI, remaining oil saturation and water driving index, four types of flow units with their own judging standard were classified as to the Fuyu-Yangdachengzi Formation. Combining with reservoir architecture, there were five genetic types of flow unit. The relationship between flow unit and dynamic data demonstrated that the flow unit could forecast productivity, instruct the distribution of remaining oil and the effectiveness of producing.
