摘　　要：胡尖山油田A21区块经过十多年的开发,已进入中高含水期,后期稳产难度逐年加大,因此对剩余油分布规律的认识有待于进一步深化。通过深化储层认识,借助三维地质建模对剩余油分布及潜力进行了评价,总结了剩余油分布规律;结合剩余油分布及储层发育特点,通过加密调整部署,试验区取得了良好的效果,为油田后期的整体调整以及同类油藏的加密调整提供了一定的借鉴作用。Hujianshan oilfield has been in the period of high water cut stage after decades of exploitation,which increasing the difficulties of exploitation smoothly an steadily.It is undoutably indispensable to deepening the cognition of the remaining oil distribution law.This article concludes the low of remaining oil distribution by deepening the understanding of sublayer,using the three-dimentional geologic model to foreshadow the remaining oil distribution and potential.Combinating the feature of remaining oil distribution and sublayer,refining adjustment has presented a satisfactory result,helping the identical reservoir refining adjustment and the intergraty adsustment.
