利用排2井原油的有机质碳同位素、物性资料、原油族组分、饱和烃气相色谱以及生物标志物色谱—质谱分析资料,并与邻区已知油源的钻井进行对比分析,认为本井原油与侏罗系煤系与古近系安集海河组湖相烃源岩混源的原油类似,排2井的油气应主要是侏罗系煤系与古近系安集海河组湖相烃源岩混源的原油。
Based on the organic carbon isotopes, physical data, crude oil components, saturated hydrocarbon gas chromatography and biomarker chromatography-mass spectrometry data of Pao-2 oil well, and comparative analysis with well-known oil sources in the adjacent area, the well crude oil Similar to the crude oil from the Jurassic coal series and the Paleogene Anjihai Formation lacustrine source rock, the hydrocarbon in Pao-2 well should mainly be the Jurassic coal series and the Paleogene Anjihai Formation lacustrine source Rock mixed source of crude oil.
