| 摘 要： | 到2001年底，已从全球六大洲18个盆地大于水深500m地域发现580亿桶油当量，90%的油气储量发现于深水浊流沉积体系，这是与近三十年来在全球范围内对深水海域的不懈探索与科学技术进步有着密切的关系。 南海珠江深水扇系统特指广布于南海珠江口盆地近海海域上第三系深水沉积物，主体位于盆地南缘珠二坳陷，属与陆架边缘三角洲体系相联系的、发育于低水位时期的深水沉积系统，其形成具有重要的地质背景，它处于若干重大地质事件的交汇地域，具对应于青藏高原隆升的沉积响应，有独特的由持续沉降所体现的纵向叠置特征，并因应于全球海平面升降变化、呈幕式推进的海侵型沉积系列，构成极为理想的油气储盖组合。因此，以时间耦合、空间耦合与地球动力学耦合为扭带，用整体、系统的论点研讨与分析南海深水扇系统的形成特征，获得一球五源（缘）是南海深水扇系统的主控因素的结论。

| Abstract: | Until the end of 2001, more than 58×109〖KG*2〗barrels OOIP have been discovered with the water depth of greater than 500 m in 18 basins whole world. Among them, 90% of oil and gas reserves discovered in turbite sedimentary system. These are the results of deeply exploration and the progress of science and technology. The Deep water Fan System (DWFS) refer to such a sedimentary system which locate in Zhu 2 depression related with the continental margin delta system and developed in lowstand tract since 23.8Ma. The formation of DWFA had an important geological background connected with the uplifting of Tibet Plateau, the expansion of South China Sea, and the global sea level change. The vertical stacked pattern is unique and consist of idealized resevoir-caprock complex. Using the systematic theory, coupled with geological time, space and earth dynamic, discusse the formation of DWFA, and reveal the main controlling factors including the Tibet Plateau Uplifting, mantle bulge, and continuous subsidence of depression, subtle deep faulting systems, sedimeatary supplies of classic sediments from granite area in south of mainland, and the global sea level change. |
