对新疆三塘湖盆地侏罗系１１个煤样进行了Ｒｏｃｋ－Ｅｖａｌ热解分析、显微组分定量分析、镜质体反射率测定及元素分析，不同方法所评价的煤有机质类型存在着一定的差异。通过对显微组分构成、沉积－成岩环境及有机质成熟度等因素的综合剖析，认为三塘湖盆地侏罗系煤中含量较高的富氢显微组分（４％～１９％）和成熟度是影响氢指数（ＩＨ）、Ｈ／Ｃ原子比的主要因素，并对煤有机质类型的评价产生了一定的影响。探讨了煤有机质类型评价的思路与方法
Rock-Eval pyrolysis analysis, quantitative analysis of microscopic components, determination of vitrinite reflectance and elemental analysis of 11 coal samples from the Jurassic in the Santanghu Basin in Xinjiang are carried out. There are certain types of coal organic matter evaluated by different methods The difference. Through the comprehensive analysis of microscopic composition, sedimentary-diagenetic environment and maturity of organic matter, it is concluded that the hydrogen rich microscopic fraction (4% -19%) and the hydrogen-rich fraction in Jurassic coal in Santanghu Basin Maturity is the main factor affecting the hydrogen index (H 1) and H / C atomic ratio, and has an impact on the evaluation of coal organic matter types. This paper discusses the ideas and methods of coal organic matter type evaluation
