大庆油田已进入特高含水期开采阶段,随着产水量的增加和注水水源种类的增多,结垢问题日趋严重。据调查,在原油集输和注水系统都存在着不同程度的结垢现象,影响了生产的正常进行。本文利用“瑞兹纳尔稳定指数”,根据油田水质分析数据,计算大庆油田各地区各种水在运行条件下的结垢趋势。 Daqing Oilfield has entered the mining stage of the special high water cut stage. With the increase of water production and the increase of types of water injection sources, scaling problems are becoming more and more serious. According to the survey, there is a different degree of scale formation in the crude oil gathering and watering systems, affecting the normal production. In this paper, “Rizanar Stability Index” is used to calculate the scaling tendency of various water in Daqing oilfield under operating conditions based on the oilfield water quality analysis data.
