摘要
通过吐哈盆地煤的低温排烃模拟实验及源岩与原油之间组分分析，发现煤与泥岩的排烃作用存在明显差异。煤成油在排驱过程中，由于地质色层作用使组分分布特征产生了明显变化而难以与母源对比。煤成油的油源对比不适宜引用以往＂油一源必然相似＂的原则。
The simulation experiments at a low temperature have been conducted to study hydrocarbon expulsion out of coals in Turpan-Hami basin. The components of source-rocks and oils have been analysed in detail. The results indicate that hydrocarbon expulsion out of coals is different from that out of mudstone,and because the geochromatography resulted in the changes of components of oils from coals, some problems and difficulties occur in the oil-source correlation. The correlation of oils from coals based on the principle,'oils and their sources have similar composition' , is not reasonable.
