Abstract:

Post-reformation is one of the most typical characters of the petroliferous basins of China compared with those of the world.It strongly affects hydrocarbon generation,pool-forming and the preservation of oil and gas resources.In turn,the post-reformation is closely related to the inherent geological features of the petroliferous basins of China.The formation of petroliferous basins relied mainly on the broken landmasses or micro-continents.In the global tectonic evolution,they were placed in between the surrounding macro-oceanic plates in Palaeozoic,and in between the Siberian and Indian continental plates and several oceanic plates in Pacific since Mesozoic.Their multi-separation and aggregation as well as formation and evolution were always controlled by the stress accumulation and dissiplation of the geodynamic systems of the surrounding plates,thus resulting in the unique features of multi-stage basin-formation and multi-superposition of different stage basins,the multicyclic tecto-sedimentary evolution and multiple post reformation of the basins.

Key words: petroliferous basin, tectonic feature, post-reformation
