摘要
针对油田回注水水质悬浮物严重超标问题,本文实验选择大庆油田回注水为样本,对其悬浮物组成进行了精细分析,研究了回注水中絮凝剂、原油组分及细菌等因素对悬浮物的影响,并对其成因进行了探讨。结果表明:悬浮物组成主要为有机物、硅酸盐、碳酸盐等。絮凝剂的"延迟絮凝"作用、原油组分的吸附作用、细菌的增殖等都是水质悬浮物的形成因素,会造成悬浮物含量的增加。
The concentration and size of suspended solids （SS） beyond the criteria have seriously affected the quality of oilfield reninjeetion water. To solve this problem,we chose the reninjection water of Daqing Oilfield as test subjects,precisely analysised the compositions of SS. We also conducted a study about the factors that impact on SS, such as flocculating agent,oil and bacteria.It turned out that these factors contribute to the increased con- centration of SS.
