摘要
中国东海海域发育东海陆架盆地和冲绳海槽盆地2个大型含油气沉积盆地,已发现的20个油气田受烃源岩分布和通源断层的控制,主要分布于东海陆架盆地的西湖凹陷及瓯江凹陷,勘探工作重点是寻找构造-岩性型大中型油气藏。东海陆架盆地勘探程度较低,具有较好的油气地质条件,油气资源潜力很大。冲绳海槽盆地则具有浅层天然气水合物和常规天然气有机结合形成水合物型大中型油气藏的潜力。
The East China Sea is characterized by the development of two large oil and gas-bearing sedimentary basins:the East China Sea Shelf Basin and the Okinawa Trough Basin.The 20 discovered oil and gas fields are controlled by the distribution of source rocks and source-related faults,mainly distributed in the Xihu Depression and Oujiang Depression of the East China Sea Shelf Basin.The focus of exploration is on the search for large and medium-sized structural-lithological oil and gas reservoirs.The degree of exploration in the East China Sea Shelf Basin is relatively low,but it has favorable geological conditions for oil and gas,with great potential for oil and gas resources.The Okinawa Trough Basin has the potential to form large and medium-sized hydrate-type oil and gas reservoirs through the organic combination of shallow-layer natural gas hydrates and conventional natural gas.
