摘要
: 针对水包油型聚合物驱采出液破乳难度大、油水分离困难等问题, 研究出了新型破乳剂, 并进行了现
场试验。结果表明: 在游离水脱除器进液中投加 11 mg / L 新研制的破乳剂, 经原油脱水工艺处理后, 脱水原油含
水率均小于 %, 分离采出水中油的质量浓度不超过 500 mg / L, 达到了脱水后油中含水及水中含油指标的要
求。 1 座处理规模为 3 × 104 m3 / d 的联合站使用新型破乳剂, 每年可节省破乳剂费用 23 万元。

Abstract: In view of the problems existing in the treatment of O/W type polymer-flooding produced fluid
such as: to demulsificate the liquid is difficult, oil can hardly be separated from water, and so on, a novel demul-
sifier has been developed, and then, a filed trial was carried out. The results showed that: by injecting 11 mg / L
of the new developed demulsifier into the feed of free-water knockout, the water content of the crude oil after
dehydration was lower than %, the mass concentration of oil of the produced water is no more than 500 mg /
L, which met the requirement of corresponding standard. The new developed demulsifier can replace the current
service demulsifi
