摘要:

油田进入中、高含水期开发阶段，结垢情况日趋严重，从采油井、注水井到各个油水泵站、配水间以及地面的输液管线都存在不同的结垢现象，其中油井结垢尤为突出，严重影响原油产量和油井的检泵周期。通过大量试验，分析了现河采油厂油井结垢的主要类型与形成垢质的主要原因，优选了适合油井结垢防治的主要方法，提出了地面连续加药和吞吐加药相结合的防垢方式，取得了明显效果。

Abstract:

As the oilfield enters moderate-high water cut period, scaling becomes increasingly serious. Various scaling phenomena exist in every part from oil production wells and water injection wells to all oil-water pump stations, water allocating station and flu
