【摘要】：探讨南海北部兴宁凹陷古近纪沉积充填特征,为超深水油气勘探提供基础地质依据。结合邻区研究成果,通过系统的地震层序地层学和地震相等综合分析,表明兴宁凹陷古近系文昌组、恩平组和珠海组之间均为不整合接触;古近系共识别出12个Ⅲ级层序。文昌组、恩平组为陆相湖盆沉积,具有缓坡带三角洲发育、缓坡浅水区滨浅湖发育、陡坡带扇三角洲发育及凹陷中心部位半深湖-深湖发育的特点;珠海组则为浅海三角洲沉积。总体的海侵沉积过程形成了恩平组湖相泥岩烃源岩与文昌组和珠海组砂岩储层的时空组合,指示研究区具有一定的油气勘探潜力。
[Abstract]:This paper discusses the characteristics of Paleogene sedimentary filling in Xingning Sag, northern South China Sea, and provides the basic geological basis for oil and gas exploration in ultra deep water. Combined with the research results of adjacent areas, through systematic seismic sequence stratigraphy and seismic equivalent comprehensive analysis, it is shown that there are unconformity contacts between Wenchang formation, Enping formation and Zhuhai formation of Paleogene in Xingning Sag, and 12 鈪，
