随着S油田开发生产的深入，平面矛盾、层间矛盾也逐渐显露出来。为使油田稳定生产，减缓递减，提高采收率，在“注够水、注好水”的思想指导下，S油田开展了大量的加强注水、优化注水工作，使油田各个区块地层压力都有不同程度的恢复和上升，层间矛盾得到有效改善。并且通过这一系列优化注水的研究和应用，使油田取得了较好的注水开发效果和经济效益。

With the development and production of S oilfield, the plane and interlayer contradiction gradually reveal. In order to stabilize the production oilfield, slow oil production decline and enhance oil recovery, under the guidance of "water injection enough, water injection well", a lot of work to strengthen water flooding and optimize water flooding have been conducted in S oilfield, which enable the formation pressure in each block of the field to recover and rise to different extent and the interlayer contradiction be improved effectively. The study and application of water injection optimization in S oilfield has achieved good effects and economic benefits.
