| 摘 要： | 利用测井曲线确定相应岩层形成时的沉积环境,常因曲线并非典型模式及所携带有关沉积环境的地质信息不完全所困扰。认为这种信息不全的实质是灰色系统理论中“灰”的基本含义,提出了用灰色聚类分析法判定沉积环境。并用以对山东阳谷--茌平煤田聊城勘探区山西组S2砂岩层形成环境进行判定,取得较好结果。同时,对灰色综合关联度作为聚类指标进行了探讨。

| Abstract: | When sedimentary environment of corresponding rocks are determined by well logging data,there is often a puzzle about their environmental sense because all log curves are not typical and full of geological information concerning sedimentary envionments.The authors consider that the essence of the inadequate information is the basic mevning of the term "grey" in grey system theory,and propose that an analysis method of cluster of grey comprehensive relationship be applied to deduce sedimentary environments.This method is applied to discriminate S 2 sandstone environment in Shanxi Group,situated the Liao City explorating district of Yanggu Ciping coalfield in Shandong province,with a better result gotten.At the same time,grey comprehensive relationship degree regarded as cluster index has been discussed in this paper. |
