摘要/Abstract

摘要： 为了实现辽河油田欢喜岭采油厂稠油的乳化降黏，在乳化剂质量分数为30%、乳化温度为50 ℃、水浴时间为1 h、搅拌速度为200 r/min、搅拌时间为5 min、剪切速率为16.9 s^－1的条件下，考察了单一乳化剂质量分数0.7%，油酸钠质量分数0.8%。最优复配型乳化剂与稠油可形成稳定的乳状液，且黏度可从1 020.9 mPa•s降至72.0 mPa•s，降黏率达到92.95%；最优复配型乳化剂与稠油形成的乳状液稳定性优于单一乳化剂

Abstract: In order to achieve the emulsification viscosity reduction of heavy oil in Huanxiling oil production plant of Liaohe oilfield, the emulsifier solution with the mass fraction of 30%, emulsifying temperature of 50 ℃, emulsifying time of 1 h, stirring speed of 200 r/min, stirring time of 5 min, under the shear rate of 16.9 s－1, the effect of single emulsifier and compounding emulsifier on the stability and viscosity⁃reducing rate of emulsion is investigated. The results show that the optimal compounding mode of the compounding emulsifier is as follow: 0.7% OP⁃12 and 0.8% sodium oleate; the best compound emulsifier and heavy oil could form a stable emulsion, and the viscosity can be reduced from 1 020.9 mPa•s to 72.0 mPa•s, and the viscosity reduction rate reachs 92.95%. The emulsion with the best compound emulsifier and heavy oil has better stability than the single agent OP⁃12 and heavy oil emulsion.
