Abstract

Abstract: Using the OP⁃10 and L61 emulsifiers to configure different hydrophilic equilibrium values (referred to as the HLB),the viscosity test of heavy oil in the second area of the oil production plant of liaohe oilfield was carried out to find out the optimal HLB of the heavy oil.At the same time, FBRM was used to measure the viscosity of heavy oil, and the effect of droplet quantity and particle size on viscous oil viscosity was analyzed.For further study on the viscosity change mechanism of heavy oil emulsion, it can be used to provide reference for the process of heavy oil reduction.Test results show that:the HLB of the emulsifying agent added to the heavy oil emulsion was 9.0,the effect of viscosity is best.At this time, the number of droplet drops to stable, compared with other HLB emulsifiers, the quantity of emulsifier is obviously low, the droplet is evenly distributed and the emulsion is stable.

摘要： 利用烷基酚聚氧乙烯醚（OP⁃10）和丙二醇嵌段聚醚（L61）两种乳化剂配置不同亲水亲油平衡值（Hydrophilic Lipophilic Balance，HLB）的混合乳化剂，针对辽河油田欢喜岭采油厂二区稠油进行降黏实验，以探明该稠油最适宜乳化剂的HLB。同时，采用聚焦光束反射测量仪（Focused Beam Reflectance Measurement，FBRM）对稠油乳状液进行微观实时测量，分析液滴数量及粒径对原油乳状液黏度的影响。结果表明，在一定范围内，混合乳化剂的HLB为9.0时，降黏效果最好，小液滴数量趋于稳定，小液滴数量与HLB不等于9.0的乳化剂相比明显偏低，液滴分布均匀，乳状液性质稳定。
