煤和含煤岩系成油理论研究和演变历史

Review on theory study and evolution history of the oil from coal and coal-bearing formations

运用系统的历史和现实类比分析方法 ,对世界含煤岩系煤成油田的源岩成熟度、烃源岩类型和煤成油田形成条件进行了综合研究。结果表明 ,煤虽能生油 ,但难以形成有商业意义的油田 ;含煤岩系中泥岩是煤成油田形成的主要贡献组分 ,在含煤盆地中 ,难以形成低熟煤成油田。

Using systematically historical and modern comparative methods,it has been discussed that oil source rock maturity,lithological properties and oilfield conditions of worldwide oilfield generated from coal and coal bearing formations.The study results indicated that the coal may generate oil,but difficult to form commercial oilfields;the mudstones in coal bearing formation are main component contributed to form oilfield generated from coals,as well as it is difficult to form oilfield generated from low rank coals.
