摘要
青南次凹下白垩统下沟组发育扇三角洲相和湖相沉积,通过对单井相、古物源、古水流等沉积特征的研究,并对岩相纵向及平面分布进行描述,总结出有利的储集岩相、岩性———扇三角洲前缘亚相灰色砾岩、半深湖泥云岩的分布规律及其主要特征。
There exist fan delta and lacustrine deposits developed in Xiagou formation of lower Cretaceous in Qingnan Hypo-sag, Jiuquan basin. 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 rock facies, lithology which are gray conglomerate developed in fan delta front and pelitic dolomite developed in semi-deep lake are summarized.
