| 摘 要： | 本文根据四川盆地中部地区香溪群的天然气、凝析油和生油(气)岩的地球化学特征,讨论了本区天然气的成因。认为本区天然气属于比较典型的煤成气。从天然气,凝析油和生油(气)岩的一系列对比,认为本区南部的天然气受下伏雷口坡组的影响,而北部为自生自储。所以本区雷口坡组可能含有丰富的油气资源。在本区雷口坡组寻找风化壳类型的油气圈闭是值得今后进一步勘探的。

| Abstract: | In this paper,we discussed the origin of natural gas in Xiangxi formation, Mid Sichuan Basin, according to the geochemical characters of gases, condensates and source rocks in the area, in which natural gas belongs to a more typical type of coal-generating gas. Having made a series of comparison between gases, condensates and source rocks, we thought that the natural gas of Xiangxi formation in the south of this area partly comes from underlying Leikoupo formation. |
