摘要
采用有机岩石学与有机地球化学相结合的方法,对华北聚煤盆地石炭二叠系不同还原类型的三种煤相及其镜质组的生烃潜力进行了综合研究与评价。结果表明,晚石炭世太原组(C_2)煤和早二叠世山西组(P^1_1)煤是良好的烃源岩,前者还是较好的油源岩;镜质组具有生烃的潜力;富氢镜质体是良好的油源组分。找寻以富氢镜质体为油源的油气藏在华北地区有重要意义。
A comprehensive investigation and evaluation are made by using methods of organic petrology and geochemistry of hydrocarbon-generating potential of three coal-facies and their vitrinites of Permo-Carboniferous coal measures in North China coalfield.The results show that coal seams in Taiyuan Formation of Late Carboniferous Epoch and Shangxi Formation of Early Permian Epoch are good rock source for generating hydrocarbons.The former is also good rock'sources for generating oil.And vitrinite has potential for generating hydrocarbons.Perhydrous vitrinits are good oil generating macerals.Searching for field-oil-gas derived from perhydrous vitrinites is of good prospect in this area,
