| 摘 要： | 结合全球海平面变化、气候变化、物源供给特征和地形条件,深入地分析和研究了发育在琼东南盆地陆坡区上新世和更新世地层中水道的形成主控因素及其在深水油气勘探中的应用价值和前景。提出琼东南陆坡上新世水道的主要因素是物源供给,包括来自红河和海南岛的物源,构造活动是关键诱发因素,上新世早期莺歌海盆地发育的大规模滑塌体与该水道的形成关系密切;给出更新世水道形成模式,其形成与第四纪冰期海平面的大幅度下降有关,地震活动诱发了中南半岛的小型山脉河流复苏,并对南海西部陆坡直接供给形成了该期水道。深水水道对于全球海平面变化、陆坡区物源供给情况和陆坡层序界面具有指示作用,并可作为良好的深水油气勘探目标,具有重要的深水油气勘探意义。

| Abstract: | We studied controlling factors and significance of channels developed in Pliocene and Pleistocene of Qiongdongnan slope area based on the global sea level fluctuation,climate change,sediment supply and seafloor topography.The controlling factors of Pliocene channel are mainly sediment supply,including sediments from Red River and Hainan Island,the tectonics is the key induced factor,and the formation of this channel has close relation with the large-scale slump developed in Yinggehai basin in early Pliocene... |
