摘要
Abstract
Nitrogen foam-alternating-water process is proposed as a potential tapping technology restricted by severe heterogeneity and special operational conditions in Bohai oilfields. As indicated in the experiments, the oil recovery in the foam injection process or following water flooding shows an increasing trend with the decrement of foam slug and the increment of injection rounds,that is,with the total foam volume and water injected,the total oil recovery during the foam-slug injection in three experiments is 5.2% ,8.01% and 12.92% respectively,and 12. 89% , 14.69% and 17. 35% respectively during the successive water-slug injection. Moreover, the oil recovery in each foam slug increases with the injection rounds, and the total oil recovery is 47.73% , 50.33% and 60% , the increment reaches 20.08% , 23.53% and 31. 68%.关键词
