| 摘 要： | 近年来,深水水道、朵体已成为油气勘探的重要目标,南海北部白云深水区发育大量深水水道-朵体沉积体系。研究现今陆坡深水沉积过程有助于揭示深海沉积分布、沉积演化规律。在回顾深水层序地层研究的基础上,利用近地表高分辨率三维地震资料所揭示的地震反射(下超点和上超点迁移)特征研究深水沉积序列,初步探讨不同时期深水水道-朵体体系沉积动力机制,深水水道-朵体体系具有垂向的前积、加积和退积特征,并提出一种深水水道-朵体体系沉积层序模式,低位体系域早期,发育碎屑流或滑块为主的水道-朵体体系,后期则转化为浊流为主的水道-朵体体系。在深水等时地层格架内研究现代深海沉积过程及其产物,对深水储层预测具有十分重要的意义。

| Abstract: | Submarine channels and lobes have been important exploration targets in recent years.There are many submarine channel-lobe systems in Baiyun deepwater areas of northern South China Sea.Researches on abyssal sedimentary processes in the modern continental slope contribute to disclosing the evolution and distribution of the deepwater sedimentation.Deepwater sequence stratigraphy has been documented in this paper.Seismic reflection features from the high quality 3-D seismic data,such as the migration of onlap ... |
