摘　　要：针对双河油田的注采结构的现状及特征,通过近几年来在注采结构调整方面的实践与应用,总结出了油田在特高含水后期开发阶段,实现油田控水稳油目标的途径和方法,注水结构调整主要是结合地质特点,减少欠注层段,减少和控制不合理超注井层段和改善吸水剖面;在采液结构调整上,控制高含水层段的注入,加强中低渗透层段的注入,封堵高渗透、高水淹干扰层段,解放动用较差的中低渗透层段,改善平面上采出不平衡的状况。通过实施注采结构调整,双河油田在特高含水后期实现了高效开发。In view of the status and characteristics of injection-production structure in Henan oilfield, ways and methods to realize the target of water-cut control and production stabilization at late development stage with extra-high water-cut are summarized in this paper on the basis of practices of injection-production structure adjustment. Measures adopted in injection structure adjustment mainly are reducing the number of underinjec-tion layers, reducing and controlling irrational overinjec-tion layers and improving water absorption profile; measures taken in fluid production structure adjustment include controlling water injection in layers with high water-cut, strengthening water injection in low permeability layers, plugging highly permeable layers and watered out interference layers, putting layers with medium permeability into production and improving the status of unbalanced recovery in plane. Highly efficient development at late stage with high water-cut has been realized in Shuanghe oilfield through injection structure adjustment.
