摘　　要：注水效果的好坏,既影响油田的开采状况,还会影响最终采收率的大小。定边X区块多油层叠合发育,由于前期开发规划不合理,导致开发层系混乱,注水开发效果较差。近年来,资源短缺、品味变差等客观情况,极大地制约了产能建设。如何提高采收率,已成为当前亟待解决的问题。注采层位对应是有效注水的基本条件,但综合考虑生产需要,对区块整体进行层系归位,调整难度很大。因此,根据区块开发矛盾及实际情况,提出了针对性分析方法和技术政策,目前在已实施区域取得了良好效果。该成果对区块保持稳产、提高采收率具有重要意义,同时可在类似区块进行推广。The effectiveness of water flooding not only affects the exploitation condition of the oilfield, but also affects the ultimate recovery. Multiple oil layers are overlapping in Dingbian X block. The development layers are chaotic and the effect of waterflood development is poor due to the unreasonable development planning in the early stage. In recent years, shortage of resources, poor taste and other objective conditions have greatly restricted the construction of production capacity. How to improve recovery has become an urgent problem to be solved. Corresponding injection-production layers are the basic conditions for effective water driving. However, considering the production needs, it is very difficult to adjust the whole block. Therefore, targeted analysis method and technology policy are put forward according to the development contradiction and actual situation of block. At present, good results have been achieved in the implemented areas. The result is of great significance for maintaining stable production and enhancing recovery in the block, and can be extended to similar blocks.
