摘　　要：通过对世界上煤成油田与其煤岩显微组分的对比研究后发现，许多煤成油田出现在煤中惰性组分含量较高的地区。笔者结合对煤中惰性组的物性分析，认为与镜质组相比，惰性组具有较小的吸附性和较大孔隙直径，它为煤中形成烃类的富集和运移提供了较好的条件。煤中具较高生烃能力的富氢组分与大量惰性组的配合，对煤成油的富集和运移有促进作用。It is found that there exist oil pools in the areas where the inertinite content.is very large in coal seams through the investigation of relationship between macerals and the distribution of oil accumulation from coal in the world. Migeration of oil from coal is easier in coal seams that inertinite content is relatively high because inertinite is smaller absorption and larger pore diameter than vitrinite. It is conducive to accumulation and migeration of oil from coal as there are both high hydrocarbon generation and more inertinite content in coal seams.
