【摘要】：本文在西藏倫坡拉盆地蔣日阿錯凹陷西北部古近系牛堡組和丁青湖組實測剖面的基礎(chǔ)上,通過對烴源巖有機(jī)質(zhì)豐度、有機(jī)質(zhì)類型、有機(jī)質(zhì)成熟度及生標(biāo)化合物等進(jìn)行分析,認(rèn)為牛堡組和丁青湖組烴源巖有機(jī)質(zhì)豐度中等,有機(jī)碳含量TOC在0.91%~5.53%之間,氯仿瀝青"A"在0.03%~0.63%之間,有機(jī)質(zhì)類型主要為Ⅰ型,Tmax平均值為428℃,烴源巖處于未成熟-低成熟階段。綜合分析認(rèn)為,研究區(qū)牛堡組是古近系最有利的烴源巖層段,與國內(nèi)外典型頁巖層各項指標(biāo)對比,牛堡組具備頁巖油形成的基本地質(zhì)條件,但成熟度略低,推斷位于蔣日阿錯凹陷沉積中心的牛堡組烴源巖厚度更大、成熟度更高,頁巖油潛力更大。
[Abstract]:Based on the measured profiles of the Niubu and Dingqinghu formations of the Paleogene in the northwestern Jiangri Acao depression, Luompola Basin, Tibet, the abundance, type, maturity and biochemistry of organic matter in source rocks are analyzed. It is considered that the organic matter abundance of source rocks of Niubu formation and Dingqing Lake formation is moderate, the organic carbon content of source rocks is between 0.91% and 5.53%, the chloroform asphalt "A" is between 0.033% and 0.63%, the average value of organic matter type 鈪，
