摘　　要：通过氮气、氮气 -水脉冲以及氮气 -泡沫调驱物理模拟实验 ,分别对均质模型、非均质模型以及倾角模型进行提高采收率研究 ,为矿场应用提供了依据。根据室内实验成果 ,在八面河油田面一区沙三上油藏开展了先导试验 ,试验区油井增油降水效果显著 ,采收率提高了 5 %。Physical modeling of nitrogen, nitrogen-water pulse and nitrogen-foam profile control drive is respectively conducted with homogeneous model, heterogeneous model and dip angle model. These EOR studies provide basis to field application. Pilot test has been conducted in a complex faulted reservoir —upper Sha 3 reservoir in Mian 1 area of Bamianhe oilfield according to laboratory result. Remarkable oil increment and water cut decline have been seen in wells of the test area, and the recovery factor improved by 5%.
