Foaming oil has been seen in development of heavy oil reservoirs in Canada, Venezuela and China. Some theories have been proposed to explain this abnormal phenomenon, but rarely analyzed from observing microscopic mechanism. Based on the study of bubble nucleation and growth in oil phase, a mathematical model of single bubble growth in heavy oil phase under combined action of hydrodynamic force and diffusive force is established and solved to display different bubble growth in heavy oil and light oil and explain the phenomenon of stable foaming oil flow.%在加拿大、委内瑞拉以及中国的一些稠油油藏开发过程中,显示出异常的"泡沫油"开发特征.国内外已提出一些理论来解释这种异常现象,但很少从微观角度来分析其形成的深层原因.在研究油相中气泡成核、生长规律的基础上,建立并求解了在水动力和扩散力综合作用下稠油油相中单气泡生长的数学模型,描述了稠油和稀油中所表现出的不同气泡生长现象,解释了产生稳定泡沫油现象的原因.
