本文在收集和整理国内外有关煤成油资料的基础上,对煤系地层含油性进行了初步探讨,认为:煤系地层中的暗色泥岩及煤层本身均具有油气生成能力,煤层中液态烃的生成与煤层的显微组分及变质程度有关;煤层具有一定的生油潜量,所生液态烃具有独特的地球化学特征;我国煤系地层众多,在具备地质条件的煤系盆地,可望成为油气勘探的新领域。
Based on the collection and collation of relevant data on coal formation in China and abroad, the authors first discussed the oil-bearing properties of the coal measures. It is concluded that the dark mudstone and the coal seams in the coal measures all have hydrocarbon generation ability, The formation is related to the microscopic composition and the degree of metamorphism of the coal seam. The coal seam has a certain potential for generating oil and the liquid hydrocarbon produced has unique geochemical characteristics. Many coal measures strata in China are expected to be expected in coal-bearing basins with geological conditions Become a new field of oil and gas exploration.
