摘要
准噶尔盆地南缘东部博格达山前凹陷三条地质剖面的上二叠统具多源输入、低等水生生物为主的高生油丰度,有机质为腐泥或腐泥腐殖的混合型。成熟度自乌鲁木齐向东至吉木萨尔逐渐增高,属低成熟—成熟阶段,而三工河剖面二叠系生油岩高成熟度可能与火山岩活动局部受热有关。 三台、北三台原油储于仓房沟群(T_(1ch)—P_(2ch)和侏罗系中,经生物标记化合物指纹对比,与大龙口剖面芦草沟组生油岩有亲缘关系。
The Upper Permian source bed along the three geological cross sections across Bogeda foredeep, the southern margin of the eastern Junggar Basin, is characterized by high concentration of multi-source organic matter of dominant lower aquatic organisms and sapropelic or mixed sapropelic-humic types, with increasing maturity from Urumqi (poorly matured) to the east of Jimusaer (matured). However, the high maturity of Permian source rocks along the Sangonghe cross section is probably derived front local heating by igneous intrusion.Through biomarker fingerprint correlation, the authors believe that oil from Cangfanggou Group (T(?)—P_(2ch) and Jurassic in Santai-North Santai area has affinities with Permian source rocks (Lucaogou Formation) in Dalongkou.
