摘　　要：针对河南油田特高含水期分层注水工艺的需要 ,研究配套了新型偏心分层注水技术和液力投捞分层注水技术 ,形成了比较成熟和完善的多级高压分注、斜井分注、厚层细分注水系列化的分层注水配套工艺技术 。To meet the requirements of separate zone water injection technology in ultrahigh water cut in Henan oilfield,new separate zone water injection technologies by decentralizing and hydraulic running and pulling are developed.A series of more mature and more perfect multistage high pressure separate injection,deviated well separate injection and subdivided layer separate injection technologies in thick have been formed.These technologies can meet the needs of separate zone water injection for the different well conditions during ultrahigh water cut.
