摘要
本文主要用煤岩学的方法对两淮煤田石炭—二叠纪煤系气源岩的有机质类型、组成和有机质的演化程度。
Detailed studies are conducted, mainly through methods of coalpetrology, about the typology, composition, evolution and factors that influence it, of organic substances in Huainan-Huaibei coal measures . Also made are detailed observations and analyses of the secondary macerals and ultra-microstructures in the coal measures related to gas and oil generation
