摘　　要：通过对吐哈盆地中下侏罗统4个未成熟煤系暗色泥岩和煤岩样品加水热压模拟实验结果对比分析,发现两者生烃产物虽然有相似之处,但也存在明显的差异。煤岩样品的在模拟温度为210-330℃(Ro≈0.61%-1.45%)以液态烃产出为主,气态烃与液态烃的比例低于1000 m3/t。在相同的模拟温度条件下,煤系暗色泥岩样品的热模拟烃类产物主要是气态烃,总的累计产烃率比煤岩样品的高100-150 mg/g Toc。After contrast analyzing the results of hydrous pyrolysis of four immature samples of diark mud and coals in Middle & Upper Jurassic of Turpan-Hami basin, the character that on the one hand, the hydrocarbon results of dark mud and coals are similar , on the other hand, their differences are still remarkable has been found. As the simulate temperature between 210℃ to 330℃ ( corresponding the Ro almost equal 0. 61 % - 1. 45% ) , the hydrocarbon results of the coals samples are basically liquid state hydrocarbon ,the ratio of gas and oil is under 1 000 m3/t. At the same simulate temperature, the hydrocarbon results of the dingy mud samples are basically gaseous hydrocarbon, and the accumulative total hydrocarbon yield is higher 100 - 150 mg/g Toc than that of coals samples'.
