摘　　要：吴起铁边城油区从上到下钻遇了延安组、延长组等多套层系的含油复合区,长4+5油藏主要集中在吴岔开发单元。针对当前吴岔注水效果不明显的状况,找出制约吴岔长4+5油藏注水效果差的根本原因,通过各种技术手段进行井网完善,对自喷井治理、关停井治理、油水井统层归位、配注量优化和动态监测等进行综合调整和治理,使吴岔注水效果得到有效改善,最终采收率显著提高。The Tiebiancheng oil field in Wuqi encountered multiple sets of oil bearing composite areas such as Yan'an Formation and Yanchang Formation from top to bottom,and the Chang 4+5 oil reservoir is mainly concentrated in the Wucha development unit.Aiming at the current situation where the water injection effect in Wucha Chang 4+5 reservoir is not obvious,the root cause that restricts the poor water injection effect is identified.Through various technical measures,well pattern improvement is carried out,and comprehensive adjustments and governance are carried out for flowing well governance,shutdown well governance,oil and water well system layer positioning,injection allocation optimization,and dynamic monitoring,so that the water injection effect in Wucha Chang 4+5 reservoir is effectively improved,and the ultimate recovery factor is significantly improved.
