【摘要】：新疆北部塔城盆地南緣下二疊統(tǒng)卡拉崗組發(fā)育一套陸相沉積的暗色泥巖,在伯依布謝水庫北側(cè)厚達(dá)131.77m,通過采集11組樣品進(jìn)行有機(jī)碳含量、巖石熱解、氯仿瀝青"A"、族組成、鏡質(zhì)體反射率和干酪根鏡檢等有機(jī)地化測試分析,探討其生烴潛力。結(jié)果表明,卡拉崗組暗色泥巖有機(jī)質(zhì)豐度較高(TOC平均0.97%),有機(jī)質(zhì)類型以Ⅲ型(腐植型)為主,熱演化程度較高(Ro平均1.19%,T_(max)平均511.8℃),具有一定的生烴潛力;但其分布局限、厚度不穩(wěn)定,且構(gòu)造保存條件較差,綜合分析認(rèn)為其勘探潛力較為有限。
[Abstract]:A set of continental sedimentary dark mudstone was developed in the lower Permian Karagang formation in the southern margin of Tacheng Basin in northern Xinjiang. The thickness in the north side of Boybuxie Reservoir was 131.77 m.The organic carbon content, pyrolysis of rock and chloroform asphalt "A" were collected from 11 groups of samples. Group composition, vitrinite reflectance and kerogen microscopic analysis were used to study the potential of hydrocarbon generation. The results show that the abundance of organic matter in the dark mudstone of Karagang formation is higher (TOC mean 0.97%), the type of organic matter is mainly type 鈪，
