Abstract: By analysing GC/C/MS on line carbon isotopes of 14 condensate oil smples from different areas and measures in the Tarim basin, we get carbon isotopic compositions of monomeric molecules of the liquid hydrocarbon system. Based on the data, we have discussed the carbon isotopic characters of monomeric molecules in condensate oils with different ages, and made oiloil comparison and origin classification. It shows that there are the coal-type oil, oil type oil and mixing type oil in Tarim basin, in which oil type oil can be divided into three sub-types by the age of source rocks: the Ordovician (Cambrian), Carboniferous and Triassic. The source rocks of the coal- type oil is Jurassic coal measures, showing the Tarim basin has 4 sets of practical source rocks (Ordovician - Cambrian, Carboniferous, Triassic and Jurassic).
