摘　　要：: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。The dehydration of crude oil at gathering/treating plant Gao 1 of Jidong was performed with demulsifier JDP 6 at rather high temperatures(70—80℃). The newly developed demulsifier, LTBF 01, is a water soluble combinational one: a special PO/EO/PO triblock polyether and a polyethylenepolyamine initiated EO/PO diblock polyether in mixture. LTBT 01 is superior to JDP 6 in dehydration rate, demulsifying rate and separated water quality as shown in laboratory comparative evaluating experiments. The dehydration temperature is decreased by 15℃ to 50—55℃ with the same amount of demulsifier LTBF 01 introduced in the field test performed over 3 months.
