摘　　要：根据海上油田防砂完井注水井井筒情况,基于陆地油田多管分注工艺技术的应用实践,开发出了海上油田同心多管分注技术并成功应用于渤海BZ25-1S油田的5口井,取得了良好效果。海上油田同心多管分注技术适于不大于3层的分层注水,特别适于层间注入压差大、普通投捞配水器注水工艺实施困难的注水井,具有一定的推广价值。The offshore concentric multi-barrel separated water injection technology was developed according to the borehole situation of offshore water injection well completed with sand control and based on the application of onshore concentric multi-barrel separated water injection technology. The technology was applied successfully in five wells of BZ25-1S oilfield and got good effect offshore. The technology is fit for separated water in jection no more than three layers, especially in such injection well with big injection pressure drawdown among layers and water injection regulator to be used difficultly, so that it has some spread value.
