| 摘 要： | 河口坝是三角洲前缘最主要的沉积砂体,也是我国陆相石油地质储量的重要载体,加强河口坝剩余油分布规律研究将会为许多大型油田下步挖潜提供依据。以河口坝构型思想为指导,分单一河口坝和叠置河口坝两种类型,建立不同厚度、不同渗透率、不同夹层频率、不同注采条件的共计18个概念模型,并数值模拟至模型极限含水。通过对数值模拟结果的对比分析,得到了点坝剩余油的影响因素及剩余油分布模式。分析认为:影响单一河口坝砂体及叠置河口坝砂体剩余油的最主要因素分别是渗透率级差和夹层位置与夹层上下储层渗透率韵律特征;单一河口坝砂体剩余油模式有三种,顶部富集型、均匀驱替型和底部富集型;叠置河口坝砂剩余油模式也有三种,界面之上富集型、界面之下富集型和界面上下富集型。

| Abstract: | Debouch bar is the most important sedarenite of delta front deposition.And it is the important carrier of petroleum-in-place of our country.It could supply foundation to develop remaining oil for many big oil field which study of distribution regularity of remaining oil of debouch bar should be strengthened.This paper regards theory of architecture of debouch bar as guidelines.There are two kinds of debouch bar,single debouch bar and overriding debouch bar.Total 18 conceptual models are established accordin... |
