摘　　要：分层注水是提高采收率工程主要内容之一,为进一步提高一次井网下水驱采收率,2010年以来,胡尖山油田持续推进精细分层注水工作,注水井分注率逐年大幅提升,成效显著。工艺上从2009年开展偏心分注、2011年推广桥式偏心分注,到2013年推广桥式同心分注,不断拓展分注技术在大斜度井、采出水回注井、多层细分井上应用范围,提高分注井测调效率和精度,逐步形成了低渗透油田分层注水工艺配套技术。The stratified water is one of the main contents of the project to improve the recovery rate, to further improve the primary well pattern water flooding recovery, since 2010, Hu Jianshan oilfield continue to promote the fine layering water injection, separate water injection rate has increased substantially, with remarkable results. The process from 2009 to carry out the eccentric separate injection, 2011 promotion bridge eccentric separate injection, to 2013 promotion bridge concentric filling, continuously expand the injection technology application in highly deviated wells, produced water reinjection wells, multilayer segmentation well, improve the injection well testing efficiency and accuracy, and gradually form the supporting technology of separate layer water injection technology of low permeability oilfield.
