| 摘 要： | 基隆凹陷是东海陆架盆地主要沉积凹陷,凹陷构造演化经历了断陷、断坳、坳陷和被覆四个阶段。凹陷由西部缓坡断阶带、中央洼陷带和东部陡坡带组成,主要填充新生界沉积层系。始新统至中新统发育四套烃源岩,油气主要储存于始新统、渐新统和中新统地层中,存在四套有利油气成藏组合。2005年油气资源评价,西湖凹陷油气当量为15.6亿方,西湖与基隆凹陷为一个统一凹陷,只是在晚渐新世-早中新世时期被短暂分隔,石油地质条件应基本相同。油气地质分析表明基隆凹陷具有良好勘探前景,凹陷西部缓坡断阶带油气勘探潜力最大。

| Abstract: | Jilong sag is the main sedimentary sag in the east China sea shelf basin. The sag has undergone four phases of tec-tonic evolution: fault depression,fault sag,depression and coating. The sag is mainly filled with Cenozoic sediments and composed by fault terrace belt in western gentle slope,hollow zone in center and abrupt slope belt in the east. Four suits of source rocks were developed from Eocene to Miocene formation in which the hydrocarbon was mainly reserved. There are four favorable petroleum systems.... |
