灰色聚类分析在储集层分类评价中的应用

灰色聚类储层分类评价是在传统储层分类方法的基础上，将储层作为一个灰色系统，利用多参数对储层进行综合分析。通过确定灰色白化函数、无量纲化、标定聚类权、求聚类系数、构造聚类向量并聚类等一系列计算和处理后，给出某一储层客观合理的分类结果。该方法解决了在复杂地质条件下边界区储层不易分类的难题，对江苏油田的分类应用表明，分类结果与生产实际吻合很好。

APPLICATION OF GREY CLUSTER ANALYSIS INRESERVOIR CLASSIFICATION EVALUATION

A new method named grey cluster reservoir classification evaluation is developed in this paper. On the basis of traditional classification method and regarding reservoir as a grey system,the reservoir is comprehensively analyzed with multiple reservoir parameters. After a series of processings, an objective reasonable classification of a special reservoir is obtained. This method can solve the problem about the reservoirs under the complicated conditions. This paper shows an example in Jiangsu oilfield. The classification results are coincident with the practice of oilfield production.
