| 摘 要： | 针对蒸汽驱驱油过程中存在的蒸汽超覆、汽窜等问题，进行了渗透率及含油饱和度对平面调剖效果影响的室内实验研究。不同渗透率对平面调剖效果的影响实验表明，注蒸汽同时注入N2泡沫体系，可以增大低渗透岩心的波及体积，从而提高原油采收率；不同含油饱和度对平面调剖效果的影响实验表明，蒸汽伴注N2泡沫对次生水体和平面高渗透层具有良好的封堵能力。

| Abstract: | Aiming at inhibition of negative effects caused by steam override and steam channeling in the process of steamflood, an experimental study was conducted for profile control effects exerted by permeability and oil saturation, respectively. Results showed that injection of steam and N2-foam could improve the swept volume in low permeability cores which led to enhanced oil recovery. Different oil saturation experiment led to a result that the system of steam and N2-foam could inhibit secondary water body and plug high permeability zones. |
