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.
Abstract
Since the waterflooding time of Chang 8 reservoir in Baihe block of Wuqi oilfield has been more than 10 years,the evaluation of waterflooding development effect is conducive to oilfield exploitation efficiency.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 efficiency wells,high natural decline rate,low formation pressure maintenance level and low water drive recovery efficiency.
