| 摘 要： | 采用气液交替注入技术可以提高高含水油藏的波及效率，改善油层的动用程度，达到提高原油采收率的目的。针对氮气／起泡剂溶液交替注入方式，分别在静态和动态条件下评价了起泡剂的使用浓度、注入速度、气液比、注入方式、岩心渗透率等参数对泡沫封堵性能的影响。综合评价结果表明，气液交替注入方式好于气液同时注入方式，能够在岩心中形成性能稳定的泡沫，对岩心的封堵作用较强。

| Abstract: | For the reservoir with high water cut,alternative injection of gas and solution can improve sweep efficiency,increase producing reserves and recovery factor.The influence of the concentration of foaming agent solution,injection rate,the ratio of gas and solution,injection mode,and core permeability on foam blockage behavior in core has been studied under static and dynamic condition.Comprehensive evaluation shows that the injection of solution alternating gas is better than the injection of solution mixing with gas.It can form stable foams in core and has better blockage effect. |

| Keywords: | alternative injection of gas and solution foaming agent resistance factor foam behavior injection parameter |
