采用美国ＰＲＡ公司的含油气系统模拟与分析软件，对吐哈盆地上二叠统桃东沟群、上二叠统至下三叠统仓房沟群和中、上三叠统小泉沟群烃源岩的地史、热史和生、排烃史进行模拟。结果表明，侏罗纪是吐哈盆地３套前侏罗系烃源岩的生油、气和排油、气高峰期。前侏罗系烃源岩累积生油、气总量分别为 １３８． ６４ ×１０８ｔ和７１．２３ × １０１２ｍ３，排油、气总量分别为５３．５８ ×１０８ｔ和４６．７４ × １０１２ｍ３，排油气效率分别为３８．６％和６５． ６％。３套烃源岩各自排出油、气量占前侏罗系烃源岩总排油、气量的比例，桃东沟群分别为 ４９．１１％和５２． ３％，仓房沟群分别为 ７． ６４％和 ８． ９９％，小泉沟群分别为 ４３． ２５％和 ８． ９９％；台北凹陷是吐哈盆地前侏罗系烃源岩的主要生烃凹陷，台北凹陷内前侏罗系烃源岩排出的油、气量约占全盆地前侏罗系烃源岩排油、气总量的 ８９％和 ８９． ５％。台北凹陷及其周边是吐哈盆地勘探前侏罗系油气的最有利地区。
Based on the PRA oil and gas system simulation and analysis software from the United States, this paper analyzes the characteristics of the Upper Permian Taodonggou Group, the Upper Permian-Lower Triassic Cangfangou Group and the Middle and Upper Triassic Junichou Group hydrocarbon source Rock geothermal history, thermal history and health, hydrocarbon expulsion history simulation. The results show that Jurassic is the source of oil, gas, oil and gas in the three sets of Jurassic source rocks in Turpan-Hami basin. The former Jurassic source rocks accumulate oil and gas total of 138. 64 × 108t and 71.23 × 1012m3 respectively. The total amount of oil and gas discharged is 53.58 × 108t and 46.74 × 1012m3, respectively, and the discharge efficiency is 38.6% and 65% respectively. 6%. Each of the three sets of source rocks discharges oil and gas respectively, accounting for 49.11% and 52% of the total discharge volume and gas volume of the former Jurassic source rocks, respectively. 3%, warehouse Fanggou group were 7. 64% and 8. 99%, respectively, Koizumi Gully 43. 25% and 8. 99%. The Taipei sag is the main hydrocarbon generating depression of the former Jurassic hydrocarbon source rocks in the Turpan-Hami basin. The oil and gas from the former Jurassic hydrocarbon source rocks in the Taipei sag dominate the discharge of the former Jurassic hydrocarbon source rocks 89% and 89% of the total gas. 5%. The Taipei depression and its surroundings are the most favorable areas for the exploration of the Jurassic hydrocarbon in the Turpan-Hami basin.
