摘　　要：针对八面河油田面120区中低渗透稠油油藏热采油汽比低、回采水率低的实际情况,进行了注氮气与蒸汽提高稠油采收率室内试验研究,对注入工艺及参数进行了优化。矿场试验结果表明,该技术可有效提高油井吞吐效果。Considedng low ratio of thermal recovery oil to thermal recovery gas and low rate of back produced water in low permeability inspissated pool in Mian--120 Area of Bamianhe Oilfield, the author did an indoor experiment of injecting nitrogen and steam increase heavy crude recovery efficiency and optimizing injection technology and parameters. The experiment shows that nitrogen and steam injection is beneficial for increasing the effect of oil well stimulation.
