Associated with the study of lighter hydrocarbon constituent, carbon isotope, biomarker and inclusions, adopted the technique of oil source correlation on whole oil samples, it can be confirmed that the hydrocarbon source of viscous crude in permian, in the east slope of jimusaer depression, is pingdiquan formation mudstone ; carboniferous oil comes from carboniferous source rock. meanwhile, the causes of oil formation are investigated based on datum of reservior geochemistry : viscous crude of permian is the result of biodegradation and low maturity working together, and that lighter hydrocarbon constituent of carboniferous oil is missing. at last, the mode and mechanism of the oil pool formation are analysed in the study area according to the structure phylogeny, sedimentary history, and data of reservior geochemistry
本論文根據輕烴、碳同位素、生物標志化合物等資料，運用全烴地球化學油源對比方法進行油源對比，得出吉木薩爾凹陷東斜坡區二疊系的稠油來自平地泉組泥巖，石炭系的稀油來自石炭系本身源巖；同時，根據地化資料研究了原油的成因，認為二疊系稠油是生物降解和成熟度較低共同作用的結果，石炭系的稀油存在輕組分散失現象；最後，綜合構造、沉積、烴源巖和油藏地球化學資料，分析了吉木薩爾凹陷原油的成藏機制和模式。 -
