注水开发油田的注水系统结垢是油田生产中常见的问题,油田注入水与地层水的不配伍往往会造成注水系统结垢,这种问题往往造成注水井吸水能力、地层压力及油气采收率下降,并最终影响油田的开发效果和经济效益。本文将对油田注水开发过程中产生的垢物的成份及性状、鉴别方法、结垢机理以及注入水与地层水静态配伍性进行分析。
Filling waterflooding oilfield waterflooding system is a common problem in oilfield production, injection of water and formation water are often not compatible with the formation of waterflooding system scaling, which often results in water injection wells water absorption capacity, formation pressure and oil and gas recovery Decline, and ultimately affect the development of the oil field and economic benefits. In this paper, the composition and character of the scale, the identification method, scaling mechanism and the static compatibility of injection water and formation water are analyzed in the process of oilfield waterflood development.
