【摘要】 崂山隆起位于南黄海中部,是南黄海中、新生代盆地的隆起构造单元,其调查与研究程度极低,新近系之下是否有沉积地层一直没有得到资料的证实。近年来战略性油气地质调查工作在该区新近系之下发现了层状地层,根据地震反射特征分析、重磁震联合反演和区域地质对比,推测为海相古生界,是下扬子区古生界的海上延伸。这一发现对推动南黄海海域油气新领域、新层位的调查与勘探具有重要的石油地质意义。更多还原

【Abstract】 Laoshan uplift is located in the middle of the South Yellow Sea basin.It is a structural unit of the Mesozoic-Cenozoic basin and of very low degree of reconnaissance and research.For a long time,it has not been identified whether sedimentary strata exist below the Neogene.According to recent strategic surveys,a bedded layer has been discovered.On the basis of seismic refection features and integrated gravity-magnetic-seismic inversion,it is inferred that the layer could be marine Paleozoic sediments,belonging to the extension of the Lower Yangtze Paleozoic.This discovery could be of great significance to further promote the survey and study for new oil provinces and new stratification in the South Yellow Sea basin.更多还原
