重质组分对稠油乳状液稳定性的影响
Influence of Heavy Components on the Heavy Oil Emulsion Stability
摘要
Abstract
The heavy components of heavy oil have a great influence on the stability of emulsion. In this paper,taking heavy oil of a Xinjiang reservoir as an example,we assayed its basic properties such as density,viscosity,solidifyig point and acid value. After separated heavy oil into saturates aromatics,resins and asphaltenes by polarity separation,we tested the basic properties and element content of the four components,Asphaltenes can stabilize the interfacial film of emulsion,and the water extraction is at the minimum and stability of emulsion is at maximum when the asphaltene content is 0.5%and resin content is 4.0%. The small amplitude oscillation experiment tests on simulation oil emulsion interfacial rheological behavior revealed that in the resin/asphaltene model oil emulsion,complex modulus(E*)increases first increased and then decreased with the passage of time. When the asphaltene content is 0.5%,the resin content is 4.0%,after 2 000 s the complex modulus(E*)is at the maximum and the emulsion is stable.关键词
