摘　　要：调整井是海上油田开发过程中调整挖潜的主要措施,通常认为调整井的可采储量即为调整井的增油量,但是越来越多的调整井实施后改变了油田渗流场及油水分布规律,简单认为调整井的可采储量就是增油量有一定的争议,另外随着调整挖潜的不断深入,调整井的可采储量逐年下降,在油价低迷时,对于调整井的经济评价也需要相对准确的增油量,因此利用水驱特征曲线采用两种不同的预测方式分别预测可采储量和可采储量增量并进行结果对比,找出两者之间的关系及原因,以期对未来评价调整井的效果提供借鉴。Adjustment wells are major measure to improve the development effect of offshore oilfield. It is usually considered that recoverable reserve of the adjustment well is the enhancement of oil production by the adjustment well. But after more and more adjustment wells are put into production, they change the seepage fields and oil and water distribution law of the oilfield, so there is a certain controversy over that recoverable reserve of the adjustment well is the enhancement ofoil production by the adjustment well. On the other hand, with the deepening of the adjustment, the recoverable reserve of the adjustment well decreases year by year, so more accurate enhancement prediction is needed to carry out the economic evaluation of the adjustment well in the current low oil price situation. In this paper, two different methods were used to predict the recoverable reserve and the increased recoverable reserve by the water-flooding characteristic curve, and two predicted results were compared to find the relationship between them, which could provide reference for evaluating the effect of the adjustment wells.
