:针对冀东油田使用的原油破乳剂JDP 6破乳温度偏高、能耗较大的情况 ,采用双组分复配法研制了水溶性低温高效破乳剂LTBF 0 1。室内对比评价表明 ,LTBF 0 1在脱水率、脱水速度、油水界面等项指标上均明显优于JDP 6。高一联合站 3个月的现场试验结果表明 ,使用LTBF 0 1破乳剂使冀东油田破乳温度下降 15℃ ,投入使用后平均每天可节约加热用天然气 3 0 0 0m3。
In view of the high demulsification temperature and high energy consumption of crude oil demulsifier JDP 6 used in Jidong Oilfield, the water-soluble, low-temperature and high-efficient demulsifier LTBF 0 1 was developed by a two-component compounding method. Indoor comparative evaluation showed that LTBF 0 1 was superior to JDP 6 in terms of dehydration rate, dehydration rate and oil-water interface. The test results of 3 months at Gao Yi Lian Station showed that the demulsification temperature of Jidong Oilfield decreased by 15 ℃ using LTBF 0 1 demulsifier, and the average daily heating of natural gas could be saved by 3 0 0 m3 after put into use.
