摘要:

通过对吐哈盆地中下休罗统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l000m/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-l50mg/g Toc。

Abstract:

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 stmilar, 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'.
