This article discusses the distribution characteristics of pyrrole nitrogen compound in reservoir bitumen and the migration direction of natural gas in the second section of the Xujiahe Formation in the Pingluoba Qiongxi area, southwest Sichuan basin. The analyses of abundance of pyrrole nitrogen compound, absolute size and relative change of isomer parameter in nitrogen commands of reservoir bitumen, etc. indicate that the horizontal migration effect mainly controls the distribution of the pyrrole nitrogen compound in the Pingluoba area, but it is not very significant in the whole Pingluoba\|Qiongxi area. The geological analysis suggests that the Xu2 reservoir is near source and has a large scale vertical migration.
