Abstract:

This papermainly discusses the geological effects of thermodynam ic process on the formation of sedimentary basins,structural changes and hydrocarbon occurrence.Thermodynam ic process is an important dynamo type of basin-forming.It is one of the necessary conditions for the formation of a hydrocarbon kitchen,which in the world generally have high or relatively high geothermal backgrounds.Thermodynam ic structures are extensive in distribution,special in structural types,and complex in structural features.Identification methods of the geoˉlogical effects of thermodynam ic process are also discussed.

Key words: thermodynamic process, thermodynam ic basin, thermodynam ic structure, hydrocarbon kitchen, process in deep layers, basin dynam ics
