摘要：

针对非均质油藏注CO2驱油时普遍存在CO2易沿高渗层过早发生气窜，导致CO2驱提高采收率低，低渗层难以动用的问题，开展了CO2不同注入方式优选的室内试验，并对优选出的注入方式进行了包括段塞大小、段塞比以及气液体积比在内的影响因素的研究。结果表明：相对于CO2气驱、CO2水气交替驱以及CO2泡沫驱，CO2泡沫与CO2交替驱（FAG）能够解决层内矛盾，延缓气窜发生时间，扩大波及体积，提高采收率；FAG驱存在最优注入段塞大小0.4 PV，最佳段塞比1∶1以及最佳气液体积比1∶1。

Abstract: For CO2 flooding in heterogeneous reservoir, gas channeling of CO2 is easy and premature to happen along the high permeable layers, which leads to low recovery efficiency of CO2 flooding and low-permeability reservoir is difficultly produced, optimal selection of different CO2 injection modes was developed in laboratory test. The influence of slug size, foam-gas ratio and surfactant-gas ratio on the optimal injection mode was also studied. The results show that foam-gas alternative flooding is an effective practice to tackle serious interlayer contradiction and prevent early gas break-though, leading to a high oil recovery. The best parameters for FAG are as following: slug size (0.4 PV), foam-gas ratio (1∶1), surfactant-gas ratio (1∶1).
