中国侏罗系煤成油若干问题

在阐述了煤成油的概念，总结和评述了煤生油显微组分，生油门限，生油范围和生油高峰等问题后，本文通过吐哈等盆地侏罗系煤生油显微组分组成特征，可溶有机质演化，成熟度和有机质丰度，油源及原油成熟度对比；含煤岩系中煤层和泥岩的厚度及总量和煤及泥岩最高沥青和总烃转化率的对比； 其族组成和煤成原油的族组成特征的对比，提出了中国侏罗系煤成油盆地中泥岩比煤层对煤成油田形成有大的贡献看法。

SOME PROBLEMS ON OIL FROM JURASSIC COAL MEASURES OF CHINA

Some definitions about oil from coal measures as oil-prone source rocks and problems of mac-erals related to oil generation and the threshold, range and peak of oil generation are reviewed. This paper suggests that the oil genetic potential of mudstone is higher than that of coal measures through comparing the characteristics of the macerals composition and evolution and maturity of soluble organic matter with the maturity of crude oil and abundance of organic matter, the thicknesses of coal measures and quantity of soluble bitumen in coals with those of mudstone and soluble bitumen of coal and its evolution with soluble bitumen of crude oil from coal in coal-bearing basins in the Jurassic System of China.
