| 摘 要： | 针对中国南海A盆地深水区缺少钻井资料的现状,运用浅水区钻井资料和深水区地震资料井震结合验证对比的方法,对古近系L组滨、浅海相沉积层序地层特征进行分析,结果表明:该方法能够解决深水区地层地震资料品质差,无井资料、断层复杂、高温高压造成地层破碎层序界面不显,追踪对比困难等难题,还建立了研究区目的层精细三维等时层序地层格架.研究中综合测井及地震资料,识别出SBO,SB1,SB2.SB3和SB4等5个层序界面,将L组自下而上划分为SⅠ,SⅡ,SⅢ和SⅣ等4个三级层序.L组地层共发育7种沉积砂体类型,在各层序高位体系域发育的三角洲、扇三角洲和低位体系域发育的下切谷、斜坡扇、盆底扇和滑塌浊积扇及海侵体系域发育的滩坝等成为有利的砂体发育区域,海侵体系域广泛分布的泥岩则是有利的烃源岩.各种类型的砂体沉积和烃源岩以及盖层可以在空间上形成半地堑和地堑两种成藏模式,发育众多的隐蔽岩性地层油气藏.

| Abstract: | The characteristics of sequence of the L Formation of Paleogene age in deepwater area in A Basin in the South China Sea were studied in reference to the classical sequence stratigraphic theory of Vail and seismic and logging data.It was showed that this method could solve the problems of poor quality seismic data,lack of well logging data,complication by tectonic faulting,and fragmentation of stratigraphic sequence.In this method,well-logging and seismic data were used,five sequence boundary of SB0,SB1,SB2,... |
