摘要
东辛油田营13复杂断块油藏构造破碎, 地下油水关系复杂, 油水井多年来一直
是合采合注, 层间矛盾日益加重。针对以上问题, 运用数值模拟等技术研究剩余油分布规律,
实施细分注水方案, 采取合采分注的开采方式, 改善油藏水驱效果, 提高油藏采收率。
Abstract
Y ing13 reservo ir is one of com plicated fau lt b lock reservo irs o f Dongx in o ilfie ld. Due to m any faults, its structure and the relationsh ip between w ater and o il are very comp licated. W ells inc luding production and injection are alw ays producing in the comm ing led production sty le, wh ich m akes the contradict be tw een inte rlaye rs agg ravate. To the abov e prob lem s, the residua l o il d istribution in the num er ica l simu la tion techono logy has been stud ied, the plan of subd iv ided in jection and the m ethod of comm ing led production have been perform ed. Th rough above the w ork, the w aterflood e ffect and reservo ir recovery have been im proved.
