摘　　要：八面河油田为稠油断块油藏,含水高,能量不足。采用注氮气技术能有效补充驱动能力。在实践中应从四个方面考虑注氮气与增产油量之间的相应关系:1、注氮气量与油砂体孔隙体积;2、注氮气位置与地层倾角对注氮气效果的影响;3、注氮气对油井含水的影响;4、注氮气对地层能量的影响。2005年,八面河油田北区共有7口井注氮气,投入产出比为1∶4.8。Bamisanhe Oilfield with high water-content ＆ inefficient energy is a reservoir of thick oil ＆ fault block. Driving force can be complemented effectively by nitrogen-injection technology. This paper introduced 4 corresponding relationships between nitrogen-injection and increase production to be considered in practice. There are 2 nitrogen--injection wells in the north area of Bamianhe Oilfield in 2005. The ratio between input and output is 1-4.8.
