摘要： 以荧光显微镜为主，结合反光、扫描电子显微镜研究，可以准确评价烃源岩。准噶尔盆地腹部盆参2井、盆4井侏罗系烃源岩有机显微组分以藻类无定形体为主，占51%~96%；彩南油田三工河组泥岩无定形体可达93.88%或微粒体含量为83.95%，在R_0＜0.73%时已经生油。

Abstract: Using fluorescent microscope. assisted with reflecting and scanning electron microscope, an accurate evaluation of hydrocarbon source rock can be obtained. Organic macerals in Jurassic soutce rock in Well Pencan 2 and well Pen 4 of the hinterland of Junggar basin are dominated by algae amorphous mass (51%~96%). In Sangonghe Formation shale , Cainan oilfield. amorphous mass can reach as high as 93.88%. or microsome accounts for 83.95%. which oil formed at R.< <0. 73%.

Key words: Junggar basin, Jurassic, Hydrocarbon source rock, Organic maceral
