本文以区内主要探井延112井烃源岩分析化验资料为主,结合前人研究结果,对区内古生界烃源岩特征进行了综合分析研究。研究结果表明,鄂尔多斯盆地甘泉地区存在下古生界奥陶系碳酸盐岩烃源岩和上古生界石炭-二叠系煤系烃源岩两套烃源岩,但是两套烃源岩有机质丰度皆很低,按现行标准并不属于有效烃源岩。而试气等其它资料表明,上古生界煤系烃源岩确实是本区的主要气源岩。
In this paper, the main source rock analysis of the main well of Well Anshan 112 in this area is the main data. According to the results of previous studies, the characteristics of the source rocks of the Paleozoic in the area are comprehensively analyzed. The results show that there are two sets of source rocks of Lower Paleozoic Ordovician carbonate rocks and Upper Paleozoic Carboniferous Permian coal measures of source rocks in Oasis Basin. However, the organic matter of two sets of source rocks Abundance is very low, according to the current standard does not belong to a valid source rock. However, other data such as test gas indicate that the Upper Paleozoic coal measure source rock is indeed the main source rock in this area.
