摘要
利用野外露头、岩心、薄片及相关测试分析对四川盆地南部龙马溪组页岩气勘探前景分析。页岩厚度可达700m，有机碳丰度为0.15%～8.75%、生烃潜力大；页岩裂缝较发育，为页岩气提供了充足的储集空间。页岩其本身具有较强的抗破坏能力，是良好的盖层。四川盆地南部龙马溪组页岩层与美国成功开采的页岩气盆地的成藏条件相似，展示了该套页岩层具有良好的勘探潜力。
Based on the outcrop, core, thin section and test, the exploration prospects of shale gas in Lower Silurian Longmaxi Formation in Sichuan Basin are analysed. This shale has a great thickness about 700m, high organic content with 0.15~8.75%,. As the reservoir, according to analyses of rock core and logging, there exit s great quantity of cracks, which offers sufficient accumulated space for shale gas. As the reason of its strong damage resistance, shale can also be capping formation. Reservoir-forming conditions of shale gas is similar to several basins in USA, which had been successfully produced, indicating the great potential of shale gas.
