摘要
通过对江苏盆地的构造沉积演化特征,以及烃源岩的有机质丰度、类型、成熟度等方面综合分析,认为江苏省下扬子区是良好的页岩气远景区。特别是徐州地区的第三系、下白垩统、石炭系、二叠系,苏北地区的二叠系,苏南地区的中古生界,有机质丰度达到达到页岩气成藏标准,据此认为这些区块可作为页岩气勘探的重点区块。
It is considered that Jiangsu Lower Yangtze region is a favorable shale gas prospective area,through analyzing the structural sedimentary evolution characteristics of Jiangsu basins as well as organic matter abundance,genre and maturity of source rocks.Especially for Tertiary system,lower cretaceous,Permo-carboniferous in Xuzhou region,the Permian in north Jiangsu and Mesozoic-Paleozoic in south Jiangsu,the abundance of organic matter meet the shale gas accumulation standard.Therefore,it is supposed that these blocks can be used as important areas for shale gas exploration.
