Abstract:Geological tectonic features, burial and geothermal evolution history of Qinshui Basin and other basins, as the representations of north China residual basins, have been studied. Forming process of coalbed methane reservoirs in main coal seams has been studied by using numerical simulation. The results indicate that reservoir forming of residual basins in North China generally experienced three stages: weak—active—dissipating. Based on the variations of coalbed methane geological features, tectonic, burial and geothermal evolution history, the coalbed methane reservoir formation can be classified as following: (1) active type, which evolves actively and coalbed methane concentrates in high level; (2) weak type, which evolves weakly and coalbed methane barely concentrates and (3) medium type. The first and the third type have more preferable coalbed methane bearing feature, that is, the potential of exploitation.
