Abstract: The author in this paper concentrates on the evolution of porosity and the diagenesis of Carboniferous Reservoir in East Sichuan. Using the enclosures in diagenetic minerals, he tries to prove that (1)the natural gas is gradually accumulated at the end of Jurassic after Yanshan Movement and (2)the degree of accumulation of natural gas is controlled by the effect of the thermally evolution of source rocks,the diagenesis and porosity evolution, the structural trap,and the migration of oil and gas.

Key words: reservoir, diagenesis, the evolution of porosity, natural gas, East Sichuan
