摘要
以准噶尔盆地中侏罗统西山窑组为研究对象，通过有机岩石学、有机地球化学和沉积学的综合研究和分析，将西山窑组沉积期划分为四种沉积有机相：高位沼泽有机相，森林沼泽有机相，流水沼泽有机相和开阔水体．其中，流水沼泽有机相和森林沼泽有机相是主要的生烃有机相类型．森林沼泽有机相是煤成气的主要源区，并具有较高的生油潜力，流水沼泽有机相则是煤成油的主要源区．
The Xishanyao formation within mid Jurassic strata in the Junggar basin is studied. Being synthetically analyzed with methods of organic geochemistry, organic and/or sedimentary petrology, the Xishanyao formation is divided into four sedimentary organic facies, which are high moor, forest swamp, running water swamp, and open water organic facies, with the running water swamp and forest swamp being the main facies of hydrocarbon forming. The forest swamp is the main source area for forming the gas from coal, and possesses great potentialities of oil formation. While the running water swamp is the main source area for forming oil from coal .
