DISTRIBUTION OF TRIASSIC STRATA IN THE SOUTHERN EAST CHINA SEA
-
摘要: 为了探讨东海南部三叠纪地层的可能分布,在充分利用东海中生代油气勘探成果的基础上,通过总结东海邻近陆域和琉球岛弧晚三叠世地层的分布特征,结合海域最新处理的地震剖面精细解释结果,综合研究认为,东海南部可能存在三叠纪地层,且可能与上覆地层之间具有"南整合北分离"的特征。由于陆域南部晚三叠世为海湾相深水环境,具有一定的生油气潜力,因此,推测海域南部三叠纪地层很可能是重要的油气勘探新领域。Abstract: Based on the data on the distribution pattern of Upper-Triassic strata in the land area close to the East China Sea and the Ryukyu Island Arc, in combination with the latest high-resolution seismic data from the East China Sea area, It is inferred that Triassic strata may exist in the southern East China Sea, and contact with the overlying strata conformable or disconformable in the south and unconformable in the north. The Upper-Triassic deposits were formed in a deepwater environment, and there is big potential for oil and/or gas generation. In this regard, the Triassic strata in the southern East China Sea could be a new important target for oil-gas exploration.
