苏北陆区古潮成沙体和海域辐射沙洲共同构成了统一的苏北南黄海潮成沙洲体系。在众多钻孔资料和地质雷达探测基础上，重点对苏北陆区古潮成沙体进行了沉积磁组构和重矿物分析，证明古潮成沙体属海退层序，是在南、北两侧三角洲发育过程... 详细信息

苏北陆区古潮成沙体和海域辐射沙洲共同构成了统一的苏北南黄海潮成沙洲体系。在众多钻孔资料和地质雷达探测基础上，重点对苏北陆区古潮成沙体进行了沉积磁组构和重矿物分析，证明古潮成沙体属海退层序，是在南、北两侧三角洲发育过程中，以长江、黄河泥沙为主的沉积物质通过沿岸搬运进入早已存在的辐聚辐散潮流场后经潮流沉积和塑造形成的。早期沉积物质主要来自长江，晚期则主要为长江和黄河的联合供沙。认为苏北古潮成沙体是全新世中后期海陆相互作用的产物。

基于对珠江口盆地白云凹陷已钻井岩心样品的有机地球化学分析,明确白云凹陷烃源岩发育特征;重构凹陷现今地温场,恢复构造-热演化过程,在此基础上通过烃源岩热模拟实验和数值模拟,预测白云凹陷资源类型、规模和分布。研究表明:①白云凹陷发育古近系浅湖相规模烃源岩,沉积期为弱氧化环境,生源以陆源高等植物为主,藻类等具有一定贡献,为油气兼生型烃源岩;②白云凹陷现今地温场显示地温梯度主体为(3.5~5.2)℃/1.0 m,整体呈现从西北往东南方向增高的趋势,不同洼陷地温梯度差异较大;③新生代以来白云凹陷经历了始新世和中新世两期明显的伸展拉张过程,经受两期加热升温事件,加快烃源岩成熟演化,基底古热流主体在距今1.0}82 Ma时达到最高值;④盆地模拟结果显示,白云主洼烃源岩成熟度明显高于其他洼陷,始新统文昌组现今整体处于高成熟—过成熟阶段,始新统恩平组现今达到成熟—高成熟阶段;⑤热模拟实验表明,文昌组浅湖相泥岩具有较好的生干酪根裂解气能力,且气产率高,具有宽窗持续生气的特征;恩平组浅湖相泥岩具有较好的生轻质油能力,晚期仍具有一定的干酪根裂解产气能力,但与文昌组浅湖相泥岩和恩平组三角洲煤系泥岩相比,气产率相对偏低;⑥数值模拟结果表明,白云主洼烃源岩生烃较早,生烃强度明显高于其他洼陷,平均约为1.00×1.^(4) t/km^(2),油气资源主体分布在主洼,主力烃源岩层位为文昌组三段和四段;⑦在运聚单元划分与评价的基础上,优选4个有利区带,分别为①号番禺3.鼻状构造带、③号流花29鼻隆带和荔湾3.隆带、②号白云东凹缓坡带以及⑧号白云1.凸起。
