油田开发过程中主要矛盾之一就是油井见水后含水上升较快。如何有效地确定油井产水的来源、控制油井含水上升及调整注水井注水量就显得尤其重要。通过灰色关联方法可以动态地研究油井产水与水井注水的关系和影响程度，进而确定油井产水的主要来源方向。通过调整相应水井的注水量，可以控制相应油井的含水率，延长油井生产时间，为油水井合理有效地调整工作制度提供依据。采用灰色关联方法，结合D16井区F17小层油井和水井生产数据，计算得到F17小层油水井关联度，并对油水井连通性进行了分析，为类似需要调整的区块提供了一种方法。%Quick water cut increase after water breakthrough is one principle contradiction in oilfield development. Effective determination of produced water origin, controlling water cut and adjusting injection rate are very important. By grey correlation method, dynamic study on the relationship and influencing degree between water production and water injection can be implemented, and water origin directions can be then determined. By adjusting the injection rate of relevant injection wells, the corresponding water cut can be controlled and productive time can be lengthened, which provide the basis for reasonable and effective working schedule adjustment. In this paper, the grey correlation method was adopted to calculate correlation degrees of Layer F17 wells based on production and injection data of Layer F17 in Block D16, and interwell connectivity analysis was carried out.
