摘要(Abstract)：

为探索控制高渗透层段水窜及提高最终采收率的有效途径,开展了氮气调剖控制无效循环现场试验。简要地介绍了注氮气泡沫控制无效循环提高采收率的机理,并通过萨北油田1个水驱井组现场试验,探索了合理的注入工艺及参数。从压力、注入量、注入剖面和产量变化等方面入手,分析了该技术取得的效果,从而得出该技术在萨北油田的适应条件和初步认识。
In order to control the water channeling among the high permeable intervals and to increase the ultimate recovery, a nitrogen injection filed test for profile control of ineffective water circulation is carried out, and the mechanism of ineffective circulation control and recovery enhancement is briefly introduced. Through one field test of water injection well group in North Saertu oilfield, rational injection technique and relative parameters have been presented. On the basis of technical effect through pressure, injection rate, injection profile and production variation, this paper concludes its applicable condition and primary knowledge in North Saertu oilfield.
