摘要： 在分析澳大利亚吉普斯兰盆地煤成烃的地质、地化条件的基础上探讨了准噶尔盆地中、下侏罗统煤岩的生烃潜力,对已知侏罗系油气田进行了烃源对比,认为中、下侏罗统煤岩无论从宏观地质演化特征,还是从微观的干酪根显微组分的组成上看,均不利于烃类的生成。准噶尔盆地侏罗系油气田的油气主要与下侏罗统偏腐殖型-腐殖型的分散有机质(暗色泥岩)有关。

Abstract: Hydrocarbon-generated potentials of Middle-lower Jurassic coal measures in Junggar basin were discussed on the basic of geologic and geochemical analyses of conditions for coal-formed hydrocarbons in Gips and basin, Australia,and sources correlations were made among the discovered Jurassic oilfields. It is concluded that Middte-lower Jurassiccoaly successions were considered to be unfavorable for hydrocarbon generatio n terms of both the characteristics of geologic evolution macroscopically and compositions of kerogen macerals microscopically, and hydrocarbons from Jurassic oilfields in Jungar basin primarily related to Lower Jurassic humic-prone to humic Dispersed org nicatters (relam stone).
