Abstract: Bsaed on the studies of structures of formation pressure and the characteristics of natural gas in TarimBasin,the paperl shows that there are several independent natural gas migration and accumulation systems inthe eastern part of Tarim Basin. There are no hydrodynamic connections between the systems and the charac-teristics of natural gas is different in different systems. The migration of natural gas was restricted within thelimit of individual system,and the lateral migration across the systems was very difficult. As a result,the nat-ural gas generated in a system could only accumulate within the same system,and this is very important to theoccurrence and evaluation of natural gas in the basin. According to different geological conditions in differentsystems , three kinds of migration and accumulation models have been developped.
