Abstract

Abstract: 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.

Key words: heavy oil, emulsification, viscosity reducing, pipeline, stability
