摘    要:本文从中国各个地质时期的地壳运动和沉积古地理出发,综合分析了晚古生代以来中国陆相含油气盆地的演化特点,提出了二叠纪湖盆发育于新疆北部,晚三叠纪湖盆主要发育于陕甘宁地区,侏罗纪时期中国西部大面积沉降,发育众多的大型湖盆,水域面积大,西部湖盆较东部发育。早白垩纪晚期以后,中国西部上升而东部开始沉降,早白垩纪晚期发育了松辽湖盆,早第三纪发育了渤海湾、苏北、江汉和海上大陆架诸多湖盆。以上这些大型古湖盆都是油气生成的有利场所。

关 键 词:含油气盆地  演化  地壳运动  沉积古地理

Abstract:Considering the crustal movements in various geologic periods and the deposition ancient geography in China, this paper comprehensively analyses the features of the evolution of continental oil-gas bearing basins in China since late-Palaeozoic era. It is concluded that the lake basins formed in the Permian period are placed in North Xinjiang; the lake basins formed in the late-Triassic period are placed in Shaan-Gan-Ning (Shaanxi-Gansu-Ningxia) area; in the Jurassic period the west part of China were subsided over an large area and therefore a lot of the large lake-basins with the greater water area were formed, and so, the lake basins of western China are more than of eastern China. After the early late-Cretaceous period, the west part of China was raising and the east part of China was subsiding. In the early late-Cretaceous peried the Song-Liao (Songhuajiang and Liohe rivers) basins were formed. In the early-Tertiary peried, the lake-basins such as Bohaiwan (Bohai Bay), Subei (Northern Jiangsu) Jianghan (Changjiang and Hanshui rivers) and continental slelvies in seas were formed.Above-mentioned large-scale ancient lake-basins all are favorable sites generating the petroleum oil and natural gas.
Keywords:Evolution  Crustal movement  Deposition ancient geography
