【摘要】 本文根据已取得的有机地球化学、煤岩学和化学工艺学的大量资料,全面阐述了腐植烟煤第一次煤化作用的跃变(地球化学沥青化作用),从而证明了腐植煤在一定条件下是可以自然形成石油,高挥发分烟煤期是煤成油重要阶段的客观事实。特别是在当前,研究“煤成油”及其有关问题不仅有重要的理论意义,而且也有很大的实用价值更多还原

【Abstract】 Based on research results so far available of organic geochemistry, coal petrology and coal chemical-technology, a systematic exposition is made of the first coalification jump ( geochemical bituminization ) of humic coals, an exposition in which enough evidence is provided that crude oil is formed from humic coals under certain conditions and that the highly-volatile bituminous coals stage is the main period for coal-formed oil. Comprehensive studies of coal-formed oil and other related substances, according to the authors, are very important, especially at present, hoth theoretically and practically更多还原
