摘　　要：综述了连续气举采油的举液机理 ,通过对所建立的两种流动模型的分析计算 ,指出目前普遍采用的混合液柱密度降低并不能作为气体举液的充要条件 ,并由此提出了能量充分交换的观点 ,这对气举采油的设计和使用提供了可靠的理论基础。This paper gives a summary of the mechanism of lifting liquid in continuous gas lift system.Through the investigation of two flow models founded,it is pointed out that the mixture density drop couldn't be taken as sufficient and necessary conditions for gas lifting liquid,and a viewpoint of sufficient energy exchange has been presented.The presentation of this viewpoint will exert a proper influence on the foundation of gas lift oil production.
