伊拉克Lukoil West Qurna-2(又名卢克石油有限公司,西古尔纳二期)油田外输原油含水含盐经常高出合格标准要求,破乳剂的应用与优化迫在眉睫。通过DPY-2A型电脱盐实验仪和瓶试法对比实验,考察实验温度和加药浓度对破乳剂脱水效果的影响,...伊拉克Lukoil West Qurna-2(又名卢克石油有限公司,西古尔纳二期)油田外输原油含水含盐经常高出合格标准要求,破乳剂的应用与优化迫在眉睫。通过DPY-2A型电脱盐实验仪和瓶试法对比实验,考察实验温度和加药浓度对破乳剂脱水效果的影响,优选出适应于伊拉克Lukoil West Qurna-2油田的复配破乳剂RD-2310。瓶试数据证明,在加药浓度为100 mg/L,实验温度80℃时,其破乳脱水性能优于现场在用的破乳剂,表现出较快的脱水速率,较高的脱水量,脱出的自由水水质较为清澈,油水界面处齐平并无乳化层。中实验证证明,从9月26日~9月28日,连续3天中实验证后,随着复配破乳剂RD-2310的加药浓度的逐渐优化降低至最佳加药浓度40 mg/L,电脱盐出口的原油含盐逐渐下降并维持稳定在27~28 mg/kg之间,电脱盐出口的原油含水数据维持在0.14%~0.2%vol之间,满足伊拉克Lukoil West Qurna-2油田外输原油含水含盐的合格标准,在生产设备中避免了出现设备内部原油挂壁问题,从而间接的提高原油的单日产量,降低了后续流程中脱出的自由水的净化处理成本。展开更多
