摘　　要：为了抑制低渗油田注空气过程中气窜的发生、提高注空气效率,开展了空气泡沫防止气窜技术研究。对研究出的复合泡沫体系ES-70/O12的抑制气窜效果和影响因素进行实验研究。研究结果表明:泡沫的注入速度、注入方式对泡沫抑制气窜效果和采收率具有显著影响。提高注入速度和采用段塞式的注入方法,可以提高泡沫封窜效果和提高采收率。研究出的体系在含油条件下仍然具有高的发泡效率。通过对研究出的体系在贝尔油田空气驱矿场试验过程中的应用。结果表明:研究出的泡沫体系对空气驱过程中气窜具有明显的抑制效果,注入泡沫后注气效果得到了改善。In order to control gas channeling and improving the efficiency of gas injection with air flooding in the low permeability oilfield, the technology of gas control by foam is investigated. Experimental study on the inhibitory ct and the influence of gas channeling has conducted with ES-70/O12 mixing foam system. The results show the foam injection rate and injection methods have a significant influence on gas channeling control effect and oil recovery. Increasing the injection speed and alternating air/liquid slug injection method can improve the effect on air channeling and enhance oil recovery by injection foam slug. The developed foam system still has a high foaming efficiency under presenting oil conditions. The developed technology of gas channeling control with foam is applied in the Baer oilfield air flooding pilot test o The result shows the foam system has obvious inhibiting effect on the gas channeling in air flooding, and air injection effect is improved by injection foam slug.
