在蒸汽泡沫微观渗流研究的基础上，研究了温度、气液比、气液速率、残余油饱和度以及渗透率对蒸汽泡沫封堵能力的影响。

The influence of temperature, gas-liquid ratio, gas-liquid rate, residual oil saturation and permeability on steam foam sealing ability is studied on the basis of microscopic percolation study.

一般相对渗透率曲线具有束缚水饱和度较高、残余油饱和度较低以及残余油状态相对渗透率较高、两相流动区间较宽的特点；

In general, these curves are characterized by high irreducible water saturation, low remaining oil saturation with high relative permeability and wider two-phase region.

结果表明：在低渗油藏相对渗透率曲线中，束缚水和残余油饱和度较高，两相渗流区范围较窄；

The results show that: 1)the residual water and oil saturations are higher in the relative permeability curves of low permeability media;
