摘　　要：结合黄3区的开发现状以及开发中存在的问题，从黄3区分层注水类型、分注方式以及最终分注方案的确定入手，探讨黄3区的分层注水政策，并结合现场试验结果，分析精细分层注水在油田开发中的的作用。黄3区在实施精细分层注水以后水驱动用程度明显提高，地层能量逐步回升，两项递减变小，含水上升率下降，开发效果明显改善。Combined with the status quo and existing problems in the development of Huang3 district, the policy of separate-zone waterflood into Huang3 district is discussed, proceeding from the types, modes and the final scheme determination of the separate-znne waterflond. Combined with field test results, the role of fine separate-zone waterflood in oilfield development is analyzed. After the implementation of separate-zone waterflood, the waterflood producing reserves ratio of Huang3 Zone was significantly improved, and the fnnnation energy is gradually picked up. The successive decline of two items becomes small, and the rising rate of water cut drops significantly. The develnpment effectiveness is improved obviously.
