细分注水作为油田特高含水期精细挖潜的重要手段,对控制注入水低效、无效循环和改善井组和区块开采效果,具有积极调整作用,随着开采方式及井网、层系的不断变化调整,原有的层段必须不断的精细化,文章重点从选井,层段的划分与组合、配水方案及注水工艺等四个方面进行优化设计,保证采油井受到较好的注水效果。
Subdivision waterflooding is an important means of fine tapping potential during the ultra-high water cut stage of oilfield. It plays a positive role in controlling inefficient and ineffective circulation of injected water and improving the production of well groups and blocks. With the development of mining methods and well patterns, Constantly changing and adjusting, the original interval must be continuously refined. The article focuses on optimizing design from four aspects of well selection, interval division and combination, water distribution scheme and water injection process, so as to ensure that oil well receives better water injection effect .
