摘　　要：论述了在油田的注水开发过程中,储层的层内、层间及平面三个层次的宏观非均质性对剩余油分布的影响,认为在经过水驱之后,剩余油的分布状况同储层渗透率非均质性的强弱有很大关系,与剩余油富集带有联系的强非均质性区是剩余油分布的主要部位,也是油田今后挖潜的主要方向。The paper studies the influences of the reservoir macroheterogeneity,including the intraformational reservoir heterogeneity, the interlayer reservoir heterogeneity, and the plane heterogeneity, on the distribution of remaining oil during the injection exploitation.It is proposed that the distribution of remaining oil is closely related with the reservoir heterogeneity characters and that the zones of high heterogeneity relevant to the accumulation of the remaining oil should be the main distribution area and thus the potential for further development.
