用于管输稠油中乳化剂HL-1的降粘性能研究

介绍了一种新型的稠油乳化降粘剂HL—1，通过考察温度、浓度、体积含油率、搅拌强度和时间对该降粘剂乳化特性的影响，得出HL—1与实验研究的稠油形成乳状液的条件；测定乳状液流变特性的结果表明，该降粘剂具有优良的降粘性能，其降粘率为9l％～97％。对比研究了乳状液在动静态条件下的稳定性，动态条件下的乳状液比静态条件的稳定性更优。通过模拟工况条件下的稳定性实验，得出该乳状液能够满足管输稠油各工况的要求。最后针对目前部分稠油管路有在高含水的情况下运行的工况，考察了HL—1对高含水稠油的乳化特性：

Performance Research of an Emulsifier to Reduce the Viscosity of Heavy Oil in Pipelines

A new type emulsifier HL-1 has been introduced in this paper. Conditions of HL-1 emulsifying the heavy oil which is studied in the experiment have been drawn by the way of investigating the influence of temperature, concentration, oil content ratio by volume, mix intensity and time on the performance of the emulsifier. Experimental results of rheological behavior determining of the emulsion have indicated that the viscosity of the heavy oil can be reduced by the range of 91% to 97%. Also, by contrast with the stability of the emulsion under dynamic and static condition, we have concluded that the emulsion under dynamic condition is more stable. Furthermore, emulsion stability experiments under the on-the-spot condition have shown that the emulsion can meet the needs of every operating mode in pipelines. In addition, considering that heavy oil highly containing water is transported in some pipeline at present, the emulsification characteristic of HL-1 emulsifying the heavy oil highly containing water has been studied.
