摘　　要：我国稠油资源丰富,但由于稠油的特殊物理性质使其开发及其困难。以重力泄水辅助蒸汽驱和稠油驱泄复合开发技术为基础,采用计算流体动力学软件ANYSY CFX计算分析油层的倾斜角度和油层厚度及原油密度对油(水)渗流速度的影响。研究表明:稠油重力驱过程中,当油层倾斜角度在40o与60o之间时油水的渗流速度减小较快。油层高度在15 m与25 m之间时,水的渗流速度增长较快,并且密度对于两相的渗流速度也有较大的影响。取得研究成果为稠油重力驱渗流研究提供借鉴。Heavy oil resources are rich in our country, but its development is difficult because of special physical properties of heavy oil. Based on the assisted gravity draining steam flooding and the development technology of drive drain compound, computation fluid dynamics software ANYSY CFX was used to analyze effect of inclined angle of oil layer, oil reservoir thickness and density of the crude oil （water） on the flow velocity. The results show that, in the process of heavy oil gravity drive, when inclined angle of reservoir is between 40o and 60o, oil and water seepage velocity decreases rapidly; when the reservoir height is between 15 m and 25 m, water seepage velocity increases rapidly; and the density has great influence on two phase seepage velocity. The research results can provide reference for seepage study of gravity drive of heavy oil.
