Well Ake 1 is the first exploratory well where commercial gas stream was found in Kashi sag in the west of Tarim basin.Geochemical features of its natural gas have idiographic properties with the contrast of ones of the others in Tarim basin:high desiccation coefficient, high content of CO2 and N2;heavy carbon isotope of CH4, which is the heaviest in Tarim basin;high value of rare gas 3 He/4 He and 40Ar/36 Ar.We elementarily ascertain the prime source rock of gas of well Ake 1 is Carboniferous by growing feature of regional source rock ,combining geochemicalfeatures of source rock and history of heat evolving.
Key words: Kashi sag; Natural gas; Geochemical feature; Source of gas
