Acta Petrologica Sinica ，29 (9):3192 － 3212 Abstract Terrestrial oil and gas generated in the Kuqa depression is widely distributed in the Tabei area ，Tarim basin. It ’s a typical example for ultra-long distance migration of hydrocarbon more than 100km. Through detailed analysis of geochemical characteristics of oil from production wells ，combined the hydrocarbon exploration data with migration conditions ，the geological characters and dynamic mechanism of ultra-long distance migration of hydrocarbon is discussed. The study shows that oil and gas found in Cretaceous sandstone reservoirs located in Halahatang and southern of Yingmaili area were generated from Triassic lacustrine source rocks in Kuqa depression ，accumulated during 5 ～ 3Ma. Hydrocarbon laterally migrated long distances along unconformities and sand bodies of Baxigai Formation of Cretaceous ，the straight-line migration distance reached 110 ～ 130km. High speed maturation of Triassic source rocks in the Kuqa depression and high effectively expulsion of hydrocarbon pr
