陇东油田清防垢技术应用效果分析

Application of scale cleanout and prevention technique in Longdong Oilfield

针对陇东油田的结垢现状与特点,分析了结垢机理及其影响因素,介绍了目前应用于陇东油田油水井、集输系统的刮垢刀、高压除垢、长效地层清防垢等物理化学技术。现场应用表明,这一系列技术为陇东油田清防垢治理提供了新的工作思路。

In view of the present situation and characteristics of the scale deposit in Longdong Oilfield,this paper analyses the mechanism and the influence factors of scale deposit.The physical chemistry techniques such as rabbler,high pressure scale cleanout,long-term formation scale cleanout and prevention are introduced.The application of the well site demonstrates that the techniques offer the new clue for future scale cleanout and scale prevention.
