本文分析了A油田注采比的影响因素,根据注采比及含水与年注水的关系曲线,在较高的采出程度下,以含水上升速度最慢且年注水最少为原则确定了各区块的合理注采比,并利用两个主产区块的开发数据对合理注采比进行了论证,最后提出了相应的开发对策,为后期油田开发提供一定的依据。
In this paper, the influencing factors of injection-production ratio of A oilfield are analyzed. According to the relationship between injection-production ratio and water-injection and annual water injection, under the condition of high recovery, the water cut rate is the slowest and water injection is the least The reasonable ratio of injection to production is obtained, and the reasonable injection / production ratio is demonstrated by the development data of the two main producing areas. Finally, the corresponding development measures are put forward to provide certain basis for the later oilfield development.
