| 摘 要： | 对塔里木盆地侏罗系煤岩以及煤岩加不同介质等 4个系列以 50℃为一温阶,从 250～550℃进行热模拟实验,并对其气体产物、液态有机质进行了系统分析。结果表明:煤岩成烃过程是一个综合作用的过程,它的生气、生油与外界环境如水,粘土矿物等的辅助作用有关。随着热模拟温度的升高,各产气率呈增长趋势。介质的加入可降低有机质成烃温度,有利于液态物的产出。

| Abstract: | Through the thermal simulation on original coal rocks in Jurassic system and the coal with different mediums from 250 ℃ to 550 ℃, with a stepwise heating stage of 50 ℃,the characteristics of their gaseous and liquid products are systematically analyzed. The result shows that the process of coal generation hydrocarbon is comprehensive and complicated. Oil and gas generated from the coal rock is related to its environment,e.g.the water and clayminerals can help this process.The yielding rate of gas products is increased with the rising temperature.Different mediums added in the simulation experiment can effectively reduce the temperature of hydrocarbon generation,and they are especially helpful to liquid hydrocarbon generation. |
