摘要
针对胜利油田东辛稠油掺水集输成本高、后续污水处理量大等问题，提出采用乳化降黏集输的方法，并筛选出一种适合东辛稠油的反相乳化剂。结果表明：温度50℃、乳化剂质量分数0．85％、有效体积含油率65％～70％、搅拌强度120r／min、搅拌时间10min为反相乳化集输乳状液的最佳制备条件；乳化集输的现场试验效果明显好于原掺水方法；乳化降黏集输具有良好的经济效益，每年可节约成本200万元。
Aimed at the problems of high cost of water blended crude transportation and large succeeding wastewater treat- ment for Dongxin heavy oil in Shengli Oilfield, a invert emulsion viscosity reducing transportation method was proposed. And a kind of invert emulsifier was selected for Dongxin heavy oil. The results show that the optimal prepared conditions of emulsion for invert emulsion transportation are temperature of 50℃, emulsifier mass fraction of 0.85%, the range of effective volume oil cut of 65% -70%, stirring intensity of 120 r/min and stirring time of 10 min. The experimental effect of invert emulsion transportation is better than that of water blended crude transportation. Invert emulsion viscosity reducing transportation has good economic benefits, and 2 million yuan can be reduced each year.
