摘要
煤可成为气源岩的观点已广为人们所接受,但就煤能否成为有效的油潭岩一直存在激烈争议。本文介绍了煤成油的研究现状,对有关煤成油的各种观点进行了评述,并结合含煤盆地的发育特点和我国南华北石炭、二叠纪合媒地层的实际资料,对含煤地层中两类不同赋有状态的有机质的生烃能力进行了对比,就目前争论最激烈的煤的排径途径和效率进行了详细讨论,最后阐述了煤成油的地化特征。
It has been widely accepted that coals can act as effective gasso-urce rocks, but it is heatedly debated whether coals can become effective oi-source rocks.Varous points about the oil-generating potential of coals and the develepment of the theory are reviewed in this article. The relative oil-generating capacity of the two different types of organic matter in coal series is compared, the migration pathway and expulsion efficiency of the oils from coals are discussed in detail based on the characteristics of the coal-bearing basin and the data obtained from our study of the ,Carboniferous-Permian coal series in the south part of the North China.The geochemical character of the coal-generated oils is briefly expounded.
