海上丝绸之路沿线深水油气资源勘探方向

    Exploration guide of deepwater oil and gas resources along the Maritime Silk Road

    • 摘要: 深水油气成为全球常规油气最重要的接替领域。海上丝绸之路(简称海丝路)沿线油气资源丰富,是全球油气勘探开发最活跃的地区,深水油气已取得了重大突破,但是部分地区勘探程度较低,发现的油气田较少,勘探潜力巨大。海丝路沿线深水盆地主要呈"一横一纵"的分布格局,"一横"主要指近东西向的新特提斯构造域深水盆地群,"一纵"主要指近南北向的东非陆缘深水盆地群。最新深水油气发现证实,海丝路沿线盆地具备形成大油气田的物质基础,存在高效的油气运移通道。海丝路沿线深水油气整体勘探程度较低,未来深水区油气以寻找构造和岩性两大类圈闭为主。孟加拉湾深水区以新生代浊积砂体形成的岩性圈闭为目标。巴基斯坦深水区以新生代生物礁和河道砂体形成的岩性圈闭为目标。东非海岸深水区以近岸的中—新生代发育的生物礁、海底浊积砂体形成的岩性地层圈闭为目标。东南亚深水区以寻找大型构造型油气田为目标。

       

      Abstract: Deepwater oil and gas has become the most important worldwide replacement resources for conventional oil and gas.The Maritime Silk Road is rich in oil and gas resources, and is the most active area for oil and gas exploration and development in the world.Significant breakthroughs have been made in deepwater oil and gas, but some areas are less explored and have less discovered oil and gas fields, so these areas exhibit great potential for exploration.The deepwater basins along the Maritime Silk Road mainly present "one horizontal and longitudinal" distribution pattern.The "one horizontal" mainly refers to the deepwater basin groups in the near east-west direction within the Neotethys tectonic domain and the "one longitudinal" mainly refers to the deepwater basin groups in the near north-south direction in the continental margin of East Africa.The latest deepwater oil and gas discoveries have confirmed that the basins along the Silk Road have the material basis for the formation of large oil and gas fields, and there exist efficient oil and gas migration channels.The overall exploration degree of deepwater oil and gas along the Maritime Silk Road is relatively low.The future oil and gas exploration in deep water area will focus on searching for two kinds of traps, including structure and lithology.As for exploration of oil and gas in deepwater area, the Bay of Bengal is targeted at lithologic traps formed by Cenozoic turbidite sand bodies, while Pakistan aims at lithologic traps formed by Cenozoic reefs and river sand bodies. East Africa coast is aimed at lithologic and stratigraphic traps formed by offshore reefs and seabed turbidite sand bodies developed in Mesozoic and Cenozoic, while Southeast Asia aims to search for large structure-controlled oil and gas fields.
