Based on the geological surveys in the field, core observation, historical well re-examination, analysis and testing, simulation experiment etc., this paper analyses the organic geochemistry characteristics, reservoir characteristics and gas-bearing features of the rich-organic matter shale in Lower Cambrian Mufushan Formation of northern Jiangsu Province. It is estimated that the average shale-gas(free and absorbed gas) content of Mufushan Formation in the northern Jiangsu is 1.4 m3/t, and the shale-gas resources amount is 1.8×108 m3/km2. According to the preliminary prediction, the favorable areas for shale-gas exploration of Mufushan Formation in northern Jiangsu Province are mainly distributed from Quanjiao in Anhui Province to Liuhe in Jiangsu Province and over the Yangzhou-Gaoyou-Xinghua area in Jiangsu Province.oft-com:office:office" />
