4The relation between tectonic event and the formation and accumulation of natural gas of Upper-Palaeozoic strata in northeastern of basin suggest that: there is a close relationship between the middle Yanshanian tectonic event and largest gas generating process of coal series source rock of Upper-Palaeoproterozoic, and the key time for gas generating and protogene gas reservoir accumulation are about 140-100Ma. The natural gas adjustment、dissipation and secondary accumulation is controlled by the strong uplifting tectonic event with age about 20Ma of slop belt in northeastern of basin.
