摘　　要：为了从理论角度探索现场调剖增油与否的原因,以大港油田为例,建立了调剖增油机理模型。调剖增油量分为调剖期间增油量和调后水驱增油量,并以调后水驱增油量为主。本文系统分析了调剖之后调剖增油产生的确定性及不确定性和调剖后无增油效果的原因。结果表明,为获得最佳的调剖效果,应将增加“调后水驱增油量”为调剖技术应用的重点,并以专门封堵强吸水层、启动含油饱和度相对较高的新层作为调剖目标。该模型的建立对今后完善现有调剖工艺,实现技术经济最大化具有一定指导意义。In order to explore the reason of profile control and increase oil or not from the theoretical point of view,by taking Dagang Oilfield as an example,the mechanism model of profile control and oil increase is established.The amount of oil increase by profile control can be divided into oil increase during profile control and water drive after profile control,and the oil increase of water drive after profile control is the main one.In this paper,the determination and uncertainty of profile control and oil increasing after profile control are systematically analyzed.The results show that in order to obtain the best profile control effect,the key point of profile control technology application should focus on the oil increase of water drive after profile control,the aim of profile control should be to seal the strong water absorption layer and start a new layer with relatively high oil saturation.The establishment of the model has a certain guiding significance for improving the existing profile control technology and realizing the maximization of technology and economy.
