Abstract: When sedimentary environment of corresponding rocks are determined by well logging data, there is of ten 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 S2 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
