分层注水井清垢技术的研究与应用

Research and application of scale removal technology of layered injection wells

水井结垢是油田注水开发过程中影响增油的一个主要因素,它也干扰着水井测调工作的正常进行。本文就水井结垢对测调的主要影响、结垢原因分析,以及对如何不动管柱清垢进行研究应用,通过洗井清垢、物理清垢、化学清垢相互结合,保障井筒畅通,有效提高测试效率,延长水井检管周期。

Scale formation in Wells is a major factor affecting oil increase in the process of oilfield water injection,it also interferes with the normal operation of water well survey and adjustment. This paper analyzes the main influence of scale formation in Wells on measurement and adjustment and the causes of scale formation,and how to keep the pipe string clean,through the combination of well cleaning,physical cleaning and chemical cleaning,ensure the wellbore unimpeded,effectively improve test efficiency,.xtend the inspection period of Wells.
