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'.

Key words: thermo-simulation, coal rock, mud in coal, measures, oil from coal Turpan-Hami basin, Jurassic strata
