摘要

气顶油藏作为一类较为复杂的油气藏类型,在开发中遇到的最主要问题就是气顶气锥进,造成油井气窜,严重影响油井产能。以渤海锦州25-1南油田Es3-I油藏为研究对象,应用数值模拟方法对屏障注水技术开发大气顶窄油环油藏的对策机理进行了系统论证,并分析了对该类油藏实施屏障注水的技术可行性以及合理屏障注水比例、注水时机等开发参数。结果表明:与衰竭开发脑及常规注水开发方式相比,屏障注水开发能显著提高此类油藏的采收率。

Abstract

For reservoirs with big gas cap and thin oil\|ring, gas channeling may obviously reduce well productivity.So how to prevent gas channeling is an important problem in the development of such reservoirs.This paper takes reservoir Es3-I of JZ25-1 oilfield as an example, using numerical simulation to study the adaptability of barrier water flooding, and analysing the technical feasibility and operational parameters of barrier water flooding.The results show that depletion and common water flooding are not available in the development of such reservoirs, while barrier water flooding can increase the recovery ratio; the effect is the best when the barrier water injection takes 60 percent of total water injection.
