摘要
油田开发到了高含水后期,井网关系错综复杂,注采失衡矛盾突出。应用传统方法可以得出整个区块的注采比,但井组注采状况不是很清晰,给单井分析、措施调整造成了一定的难度。为此,利用流线模拟对井组注采关系进行了定量研究,得到了井组中水井的注水分布方向及比例以及采油井的来水方向及比例,可以进一步剖析注入水在地层中的方向、比例及产出规律,优选开发方案,从而为动态分析提供了有效的技术手段。
At the late stage of high water-cut,the relationship between well groups becomes more and more complicated,and the contradiction between injection and production is serious.The injection-production ratio of a region can be computed by using traditional method,but the injection and production situation is not very clear,which makes it difficult to analyze a single well or to take measures for adjustments.Therefore,aquantitative research of relationship among injectionproduction well groups is developed based on streamline simulation.The distribution and proportion of water injection and oil production of wells in a well group are obtained.On this basis,its distributive direction and proportion of water injection and oil production are obtained,the development program is optimized,which provides a technical method for dynamic reservior analysis.
