| 摘 要： | 闽江凹陷是东海陆架盆地南部中生界油气运移的长期有利指向区,它的形成演化史对凹陷内油气的运聚与保存具有重要的影响。采用地震剖面分析、平衡剖面分析等方法对其进行分析,结果表明:侏罗纪末期雁荡低凸起和台北低凸起尚未形成,闽江凹陷与东部的基隆凹陷连为一体,整体稳定沉降接受沉积;白垩纪末期的断陷运动导致雁荡低凸起形成,其西部的瓯江凹陷为典型的陆相断陷湖盆,台北低凸起尚未形成规模,闽江凹陷仍与基隆凹陷连为一体,接受滨浅海相沉积。后期构造运动的改造导致闽江凹陷呈现出现今的盆地形态。对于闽江凹陷的油气突破具有重要的指导意义。

| Abstract: | TheMinjiang sag is the destination of Mesozoic oil and gas migration in the southern East China Sea. The formation and evolution of the sag bear great impacts on the migration, accumulation and preservation of oil and gas. Based on the seismic interpretation and balanced cross section study,it is revealed that the Yandang low uplift and Taibei low uplift had not yet formed before Late Jurassic. The Minjang sag, together with the Jilong sag in the east,accepted stable deposits of littoral facies. The faulting movement in Late Cretaceous led to the formation of the Yandang low uplift. The Oujinag sag was a typical continental fault basin filled with lacustrine deposits. The Taipei low uplift was not yet formed then. The Minjiang sag was connected with the Jilong sag to receive marine deposits as a whole.The present framework of sag sowes its origin to tectonic movements. |
