| 摘 要： | 中扬子地区作为南方海相油气勘探的重点战略区块 ,自基底形成至今 ,陆块南北经历了多期造山活动。其中 ,古生代以来的后四期造山作用控制与发育了区内海陆相四套含油气系统 ,加里东及印支早期造山作用利于原生海盆含油气系统的发育与形成 ;印支晚期—喜山期造山作用对其具有改造和破坏作用 ,但利于陆相含油气系统的形成。研究区海盆发育期形成的古隆起及其周缘斜坡带是海相残留盆地油气运聚与保存的有利场所

| Abstract: | The Middle Yangtze region is an important site for marine petroleum exploration in South China. The region has gone through polyphasic orogenic movements since the basin basement formed. The later four orogenic movements controlled four marine and continental petroleum systems in the region since the Paleozoic. Caledonian and early Indosinian orogenies are favorable for the formation of marine petroleum systems. Late Indosinian and Himalayan orogenies reformed and destroyed them, but are favorable for the formation of continental petroleum systems. The ancient uplifts and their slopes formed in the region during the development of the marine basin are favorable sites for the migration and reservation of petroleum in the marine residual basin. |
