 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.
