摘要
本文根据东海和邻近海域数十口钻井、数万公里地球物理以及岛屿和底质等调查资料提出东海盆地早第三纪曾经历两次海侵,以始新世这期规模最大。笔者认为东海盆地杭州湾—冲绳岛断裂以北为陆相沉积区,煤系地层发育,似以气为主、油为辅的富集区;其南为海相沉积区,似以油为主、气为辅的富集区。
Based on 40 drilling wells ,60 000 line-kilometers geophysical data and information about islands and sea floor exploration ,it was proposed that in early Tertiary the East China Sea Basin experienced two transgressions with the largist scale in Eocene The author considered that the northern part of Hangzhou Bay -Okinawa Island fault in the East China Sea Basin was a continental deposit area in which coal-measures developed, accumulating rich gas and oil;and the southern part was a marine sedimentary area,ac-cumulating rich oil and gas .
