摘　　要：泡沫油流是国内外常见的存在于重油油藏的流态 ,是一种在液气驱生产阶段的气油两相流 ,须有一个液相使其连续才能流动 ,并且其中包含分散气泡。文章对泡沫油流中泡沫的稳定性进行了讨论 ,得出原油性质和地层条件是影响泡沫油流中泡沫稳定性的重要因素的结论 。Foam oil stream is a kind of fluid state contained in heavy oil pools, commonly seen in China and abroad. It is a kind of two-phase fluid of oil and gas, existing in the producing stage of oil-gas drive. There must be a continuous liquid phase in the fluid, so as to be able to flow, and the fluid must contain dispersed air bubbles. The article discusses the stabilization of foam in oil stream, and comes to the conclusion that the key factors affecting the foam stability in foam oil stream lie in the property of crude oil and the condition in reservoirs. Furthermore, the stabilization of foam in stratigraphic condition is the key factor, which can guarantee the high recovery by way of the cold extraction of heavy oil.
