Abstract: There exist fan delta and lacustrine deposits developed in Xiagou formation of lower Cretaceous in Qingnan Hy po-sag, Jiuquanbasin. In this paper, the sedimentary features of single-well facies, palaeo-source and palaeo-current are studied, the vertical and .transversal distributions of the reservoir rock facies are described, and the distribution and main characteristics of favorable reservoir rockfacies,lithology which are gray conglomerate developed in fan delta front and pelitic dolomite developed in semi-deep lake aresummarized.

Key words: Jiuquan basin, Early Cretaceous, reservoir, sedimentary characteristic
