摘要：
Based on the configuration heterogeneous characteristics of biomarkers, the sterane and hopanoid characteristics of hydrocarbon inclusions in craton area of Tarim Basin are studied using chromatography-mass spectrometry (GC-MS), so as to analyze the maturity of hydrocarbon inclusions. The hydrocarbon inclusions of marine carbonates in North Tarim and Central Tarim mainly show mid-high maturity, and slight differences might exist among different regions and stages. In North Tarim during the Late Hercynian, the maturity of hydrocarbon inclusions varied a lot in each region. Hydrocarbon inclusions in Yaha-Jinyue-Repu area were highly mature, while mature in other regions. As compared with North Tarim, the maturity of hydrocarbon inclusions was comprehensively higher in Central Tarim during the Late Hercynian and Yanshan-Himalayan, where hydrocarbon charging in the same stage was considered posterior to North Tarim. The maturity of crude oil in Central Tarim was lower than that in North Tarim as a whole, indicating that North Tarim underwent more severe late reformation. The hydrocarbons in both Hercynian and Yanshan-Himalayan stages made a major contribution in North Tarim, while those had a greater contribution in Central Tarim. © 2016, Editorial Office of ACTA PETROLEI SINICA.
