在对塔里木盆地北部星火1井寒武系玉尔吐斯组灰黑、黑色碳质泥岩进行一系列有机地球化学特征测试分析的基础上，从有机碳、氯仿沥青“A”、生烃潜量、热解峰温、海相镜状体反射率、烃源岩可溶抽提物和饱和烃色质特征等方面着手，对该烃源岩的有机质丰度、成熟度及类型进行分析。结合前人研究成果，讨论了这套烃源岩与以往报道的寒武系烃源岩的异同，并开展了与塔河原油的油-岩对比分析。结果表明，该套烃源岩有机质丰度高，而且已达高成熟热演化阶段，与柯坪露头肖尔布拉克剖面下寒武统玉尔吐斯组烃源岩特征类似；星火1井下寒武统黑色碳质页岩有机质地化特征与塔河油田原油具亲源性。

In the northwestern Shaya Uplift of the Tarim Basin, gray and black carbonaceous mudstones were collected from the Cambrian Yuertusi Formation in the well XH1, and were tested for organic geochemistry. The analyses included the determinations of organic carbon (TOC), chloroform bitumen “A”, hydrocarbon generation potential, pyrolysis peak temperature, marine vitrinite, soluble extraction of source rock, gas chromatography and so on. The organic matter abundance, maturity and type of source rocks were studied. The Cambrian source rocks in the well XH1 were compared with other Cambrian source rocks in previous reports. Oil-source correlation of the studied source rocks was made compared to those from the Tahe oilfield. The studied source rocks have high organic matter abundance, and have entered the high-mature stage for thermal evolution, which is similar with the source rocks in the Lower Cambrian Yuertusi Formation on the Xiaoerbulak profile in the Keping area. There are some similar geochemical characteristics between the Lower Cambrian black carbonaceous shale and the crude oil from the Tahe oilfield.
