摘要

针对N1井区油藏地层压力下降过快、能量不足的问题,开展了转注方案研究。首先利用区域沉积体系展布特征结合井上钻遇资料将N1井区储层划分为三期河道沉积,幵对N1井区的注采对应率迚行详细的分析。然后利用物质平衡法研究了合理地层压力。最后运用数值模拟方法对转注方案迚行优选。通过对压力、增油量等指标的优选,最终推荐D24,A32井转注。
        In order to solve the problem that reservoir pressure was falling too fast and energy was not enough in N1 well area, the injection scheme was studied. Firstly, the reservoir of N1 well area was divided into three stages of river channel deposit by the characteristics of regional sediment system distribution combined with field drilling data, and the corresponding rate of injection-production in N1 well area was analyzed in detail. Then the reasonable stratigraphic pressure was studied by the material balance method. Finally, numerical simulation method was used to optimize the injection scheme. Through the optimization of the indicators such as pressure and oil increase, the D24 and A32 wells were finally recommended as injection well.
