摘　　要：锦州25-1南油气田是一个构造复杂、断层发育的区块。为了有效合理开发,提高油气资源采收率,本文设计了在同一口井内实现分层注水或在一口井内实现分层注水和采油的新技术工艺,同时实现注水和采油两种功能,随着海洋石油开发工艺的逐步完善,将污水及循环后钻完井液回注地层,可以起到节约油田的开发成本、保护海洋环境的功能,也为实现同井产液和分层注水注聚提供了技术保障。The south oilfield of Jinzhou 25-1 is a block that had complex structure and development of fault. In order to develop effectively and reasonable, and improve the recovery efficiency of oil and gas resources. This article designed a new technology of layered water injection or layered water injection and oil production within a well, realized two functions of water injection and oil production at the same time, with the offshore oil development process improved gradually, the sewage and drilling and completion fluids circulating reinjection formation may play field development cost savings, protection of the marine environment features, but also provided the technical support to achieve the same well fluid production and water injection layered and polymer injection.
