摘　　要：稠油广泛蕴藏于加拿大、委内瑞拉、中国等国家,出砂冷采作为一种有效的稠油冷采技术,主要通过形成泡沫油而获得高产油流,因此,加强泡沫油的相关研究对该类油藏的开发至关重要。调研了中外关于出砂冷采稠油油藏泡沫油的研究现状及最新进展,从分析泡沫油油藏非常规特征入手,系统介绍了泡沫油的定义及性质,详细说明了泡沫油非常规高压物性及压力衰竭实验方法及研究内容,总结了泡沫油孔隙网络模拟及宏观数值模拟方面的研究进展。加强泡沫油流的理论研究,明确岩石流体特征、操作条件等对泡沫油流的影响,探索泡沫油油藏开发后期有效的接替技术是今后的研究重点和方向。Heavy oil reserves exist in Canada, Venezuela, China and other parts of the world, whose reserves is equivalent or even higher than the existing reserves. Cold heavy oil production with sand is an effective technique, which can produces more oil than conventional solution gas drive reservoir by formulating foamy oil flow. So, enhancing the research of foamy oil is essential for developing such reservoir. This paper studied the research status and the recent development of foamy oil in cold heavy oil production with sand. Beginning with the analysis of foamy oil reservoir's unconventional characteristics, definitions and properties of foamy oil are introduced systematically. The methods and research content of unconventional PVT and depletion experiments are presented here. The detailed over view about the research on the pore network modeling and reservoir simulation are summarized. Finally, the focus of future work and research direction are proposed, which may be of referential meaning in the further research on foamy oil.
