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.
