Abstract: The Turpan-Hami basin is a typical basin in which hydrocarbons are derived from coalg and main source rocks are coalwith coaly organic matters in the Lower-Middle Jurassic.The analysis of organic petrology showed that the composition ofmaceraLs is of characteristic of the high content of groundmass maceraLs(such as desmocnllinite, macrinite),small individu-als of sporinite and alginite and higher contents of transition macerals(such as vitrinite inertinite desmoc;olHnite and bitu-minite).By mean of nucroscopy, laser microscopy and transmitting electronic microscopy(TEM),it was shown that themain oilg-generating maceraLs are desmocollinite under microscopic observation. Liptodetrinite,。utinite, suberinite and spori-nite have important contributions to thehydro carbon from coal; Under TEM the main oil generating mac}ral is the submi-croliptinite attered in desmoconite and macrinite and it is originated from degraded materials of bacteria. The high con-tent of desmoc collinite in coal remedies its lower hydrocarbon generation potential per unit The cause of hydrogen ric;hnessindesmoc;ollinite attributes to strong degradation and reworking of bacteria to it in the biocthemical stage.
