摘要
气举采油是将高压气体注入井下,把井中液体举升到地面的一种采油方式,它具有排量范围广、举升度深、抗腐蚀、井下测试简单、便于管理等优点。适应于高油气比、高产深井、出沙井、定向井、丛式井、海上采油平台等,是一种理想的提液手段。介绍了气举采油优化技术的应用情况,分析了制约和影响气举采油的各种因素及今后挖潜方向,对进一步提高气举采油工艺水平,高效开发油田提出了建议。
Gas lifting is a kind of recovery method through pumping high pressure gas into wells to lift fluid up to surface.It has the advantages of wide displacement range,large lift height,high corrosion resistance ability,simple downhole testing procedure and easy to manage and is suitable for utilization in high GOR wells,high-yielding deep wells,sand problem wells,directional wells,cluster wells as well as offshore production plat-forms.This paper introduces the application of gas lift optimization technology,analyzes the constraints and im-pacting factors of gas lift and presents several proposals in order to fur ther im prove this technolo gy and realize highly efficient development of oilfields.
