摘要:

注水是油田开发中使用最为普遍的开采方式,但水驱采收率一般不高,探索水驱后如何提高采收率一直是广大科技工作者思考的问题。注气是一种较好的提高采收率技术,在水驱后油田注气潜力如何还不清楚。在此分析了国内外油田水驱后注气项目实施情况,并对我国一些油田实例进行了评价,对我国油田水驱后注气开发的实施有较好的指导意义。

Abstract:

Water injection is a commonly used method for the development of oil field. However, oil recovery by water-flooding is usually low. As such, how to enhance oil recovery after water-flooding has been a challenge facing petroleum engineers. Gas injection flooding has long been considered as a viable EOR method in the petroleum industry, but the potential of gas injection after water-flooding is still unclear. In this paper, the schemes of gas injection after water-flooding in China and abroad are analyzed, and some of the Chinese case studies are reviewed.

Key words: water-flooded reservoir, gas injection, feasibility
