| 摘 要： | 白云-荔湾深水区位于南海北部陆架边缘陆坡区。近年来在白云凹陷北坡的一系列天然气发现和LW3-1气区的突破证实白云凹陷为富生烃凹陷。白云-荔湾深水区发育古近系文昌组、恩平组和珠海组等3套巨厚烃源岩层,并发育古近系浅海陆架、陆架边缘三角洲和新近系陆坡大型深水扇2套优质砂岩储集层系。渐新世—中新世分布在白云凹陷南北两侧的2个陆架坡折带、"构造脊+断裂+砂体+不整合+流体底辟"复合油气输导体系以及晚期构造运动控制了白云-荔湾深水区的油气运移和成藏,形成了中新世陆架坡折带(白云凹陷北坡—白云主凹气区)和渐新世陆架坡折带(白云凹陷南坡—荔湾主凹气区)两大油气富集区,已发现天然气均位于两大陆架坡折带控制的有利成藏区内,展示出白云-荔湾深水区具有巨大的勘探潜力。

| Abstract: | Baiyun-Liwan deepwater area in Pearl River Month basin lies on a slope zone along the northern shelf margin,South China Sea(SCS).It has been proved by the recent several gas discoveries on the north slope of Baiyun sag and the breakthrouth in LW3-1 gas area that this sag is abundant in hydrocarbon generation.In Baiyun-Liwan deepwater area,there are three sets of Paleogene thick source rocks respectively in Wenchang,Enping and Zhuhai Formations,and two sets of high-quality sandstone reservoirs,deposited resp... |
