摘　　要：利用大量的烃源岩地球化学数据,从有机质显微组分、有机质丰度、有机质类型及有机质成熟度四个方面,对吐哈盆地十三间房地区煤系烃源岩地球化学特征进行了分析,结果表明,侏罗系西山窑组在研究区内厚度较大,分布较为连续,烃源岩成熟度较高,是研究区内主力烃源岩层段。对研究区烃源岩成熟度史模拟研究结果表明：1十三间房地区烃源岩生烃门限深度为1 800 m,门限温度为95℃,进入生烃门限的时间约为162 Ma;2在西山窑组现今地层温度为50～110℃,Ro达0.6%～1.1%,正处于生油高峰期;3研究区内烃源岩成熟度表现为西高东低、北高南低,其有利勘探区主要位于研究区西北部。Use of number of geochemical datas,hydrocarbon source rocks from the maceral of organic matter,organic matter abundance,organic matter type and four aspects of organic matter maturity,Shisanjianfang area of Tuha basin coal measures hydrocarbon source rocks geochemistry characteristics are analyzed,and the results show that the thickness in the study zone from the Jurassic formation is larger,distribution is continuous,the hydrocarbon source rock maturity is higher,is the study of hydrocarbon source rock in the area. The hydrocarbon source rock maturity history in the studied area simulation results show that： 1 Shisanjianfang area of hydrocarbon source rock hydrocarbon threshold depth of 1 800 m,the threshold temperature is 95 ℃,enter the time of hydrocarbon generation threshold is about 162 Ma; 2 the current from the in formation temperature is 50 ～ 110 ℃,0. 6% ～ 1. 1%,Ro is in peak oil source; 3 the research area of hydrocarbon source rock maturity to west,north to south and low in low,its favorable exploration area mainly lies in the northwest of the study area.
