摘要: Abstract The basin-mountain systems in the Sichuan basin exert major control on today’s oil/gas distribution, chiefly through their controlling influence petroleum reservoirs preservation, thickness of deposited terrestrial formations and degree uplift denudation. composite system its peripheral mountains can be classified as two types – margin-plate interior-plate systems. include surrounding Longmen Mountains, Micang Mountains Daba which are not only western northern marginal area basin, but also represent margin Yangtze plate (South China Block). systems, with binary units large-scale thrust belts foreland basins, have different deep lithospheric structures, abrupt boundaries great contrast geomorphology between mountains. On contrary, comprised by adjacent Qiyue Dalou Daliang Mountains; eastern southern located within plate. They similar structure gradual mountains, lacking basins. Today’s medium-large scale natural gas accumulations mainly distributed areas influenced especially
