文中介绍了灰色关联法的基本理论与思想，通过量化分辨系数，使得关联系数、关联度和权系数的求取更为合理与准确。以X 断块油藏为例，选取了5 个影响剩余油分布的静、动态参数作为评价指标，详细阐述了各参数权系数与自身评分的计算过程，最终得到剩余油分布的综合评分。评价结果与实际生产吻合较好，表明该方法能够应用于开发后期的剩余油分布评价。

The basic theory and thought of grey association analysis are introduced. The correlation coefficient, correlation degree and weight coefficient are obtained more reasonably and accurately through quantification of resolution coefficient. Taking X fault-block reservoir for example, five static and dynamic parameters which can influence remaining oil distribution are selected as evaluation index to expound the computation process of weight coefficient of each parameter and own grading, and a comprehensive score for remaining oil distribution is obtained. The evaluation result coincides with the actual production, which proves that this method can be applied to the remaining oil distribution evaluation in the later development.
