| 摘 要： | 东海陆架盆地是叠合含油气盆地，其中闽江凹陷中生代分布广，厚度大，垂向上发育多套生储盖组合。整个东海陆架盆地经历的全区性构造运动有基隆运动、雁荡运动、瓯江运动、渔山运动和龙井运动，具有复杂的构造演化历史。据构造样式形成的动力学机制，可以将闽江凹陷划分为伸展型构造样式、挤压型构造样式和复合型构造样式3类。断裂是盆地构造分析的基础，闽江凹陷主要发育雁荡主断裂、台北主断裂和虎岩北断裂等。各种类型的构造油气藏严格受盆地构造样式和断裂的控制，呈有规律的分布。可以推测，基隆—新竹凹陷带是主要的生油凹陷，闽江—厦澎斜坡是油气运移的指向，而斜坡上发育的局部构造是油气富集的有利部位。

| Abstract: | The East China Sea Shelf Basin is a superimposed petroleum bearing basin. Thick Mesozoic deposits are widely distributed in the Minjiang Depression. There are several sets of reservoirs and cap combinations in vertical sequence. The East China Sea Shelf Basin has experienced several episodes of tectonic movements such as the Jilong movement, Yandang movement, Oujiang movement, Yushan movement and Longjing movement. According to the dynamic mechanism, the Minjiang Depression can be divided into three structural types, namely extensional, compressional and complex structural styles. The depression has three major faults i.e. the Yandang fault, Taibei fault and Huyan north fault. Various types of structural reservoirs are strictly controlled by both the structural style and fault distribution pattern in the basin. The Jilong-Xinzhu Depression is the major oil-generation depression, the Minjiang-Xiapeng slope is the path for oil and gas migration, and the local structures on the slope are the favorable traps for oil and gas accumulation. |
