摘  要:综合分析辽东湾北部地区古近系东营组一段层序的岩心、地震、测井等地质资料,认为该地区在东营组一段层序沉积时期主要发育有辫状河三角洲、曲流河三角洲、滨浅湖砂质滩坝和深湖等沉积相。结合研究区构造特征和水系发育特征,编制了东营组一段层序的沉积相平面展布图。Comprehensive analysis the core, seismicdata,logging data and other geological data ofthe member 1 sequence of dongying formation of the Paleogene in Northern Liaodong Bay, the results show that the sedimentary facies during this sedimentary period include braided river delta, meandering river delta, shore-shallow lacustrine sandy beach bar and deep lake. On the basis of the structural feature and development of water systems in this area, the author draws up the distributing feature of sedimentary faces of the member 1 sequence of dongying formation.and lower parts of second member of Dongying Formation.
