摘　　要：由于吴起油田白河区块长8油藏注水时间久已超过10年,对注水开发效果进行评价,有利于油田开采效率。文章通过对白河区长8油藏开发效果进行综合评价,认为主要开发矛盾表现为开井率低、低产低效井多、自然递减率大、地层压力保持水平低、水驱采收率低等特征。Since the waterflooding time of Chang 8 reservoir in Baihe block of Wuqi oilf ield has been more than 10 years,the evaluation of waterflooding development effect is conducive to oilf ield exploitation eff iciency.Based on the comprehensive evaluation of the development effect of Chang 8 reservoir in Baihe area,the main development contradictions are as follows:low well opening rate,many low production and low eff iciency wells,high natural decline rate,low formation pressure maintenance level and low water drive recovery eff iciency.
