泡沫辅助蒸汽驱能够有效抑制蒸汽“超覆”和气窜现象，提高热能的利用率，从而进一步提高稠油油藏的采收率。利用物理模拟和数值模拟技术，研究了泡沫辅助蒸汽驱的开采特征和开发效果。研究结果表明：泡沫能够有效封堵高渗岩心，使得后续蒸汽更多的进入低渗岩心，改善蒸汽的驱油效率；泡沫有效抑制了蒸汽的气窜，使得蒸汽更多的进入油层中部和下部，改善了吸汽剖面，提高了热能的利用率，提高了油藏的最终采收率。

Foam assisted steam flooding can effectively restrain steam overlap and gas channeling, improve the efficiency of heat en-ergy, thereby improving heavy oil recovery. Physical simulation and numerical stimulation are used to study development character-istics and efficiencies of foam assisted steam flooding. The research shows that foam can effectively plug high permeability core, in-ject more subsequent steam into low permeability core, and improve steam displacement efficiency. Moreover, foam effectively re-strains gas channeling, injects more steam into middle and lower parts of reservoir, thereby improving gas injection profile, increas-ing heat energy efficiency and reservoir ultimate recovery.
