摘要
提出了利用灰色关联度进行计算机小层对比的方法及步骤，该方法将油组中的小层视为灰色系统，以小层的各种对比特征为依据，用灰色关联分析法计算井间各小层间的关联度，采用搜寻最大关联度的方法，对油组进行逐步分割，以实现井间小层的合理匹配。其基本步骤为：①小层特征提取；②数据的无量纲化处理；③关联度分析；④关联度匹配；⑤对比结果输出。实际应用表明，用该方法得出的小层对比结果与人工对比基本一致。
he layers in an oil group can be regarded as a grey system.According to the characteristics of each layer,the relational value of a layer is computed by the grey relational analysis.An oil group is divided into smaller sections which are matched for all the reference layers by searching for the maximum relational degree.The procedure involves characterization of a layer, dimentionless processing,analysis and the matching of relational degree of well-to-well curves and output results.The results obtained by the procedure are consistent with those of manual interpretation.
