摘　　要：随着国内油田注水开发的深入,注水井污染堵塞和欠注现象越来越严重,注水井酸化增注越来越被重视。如何解除注水井伤害,以及延长注水井酸化周期是目前国内油田开发生产亟待解决的问题。分析了注水井伤害的主要原因,通过室内实验结果提出了适用于注水井酸化增注的酸液体系。With the deep development of domestic oil field water injection, pollution, plugging and insufficient injection problems of water injection well are more and more aggravated. To re- lease the damage and extend the acidification cycle of water injection well are urgent problems for domestic oil field at present. In this paper, the main reason of damages in water injection well was analyzed, and the acid system was proposed for dissolved plug and increasing water injection.
