在世界上，含煤岩系中是否存在以煤岩为主要贡献组分而形成的油田？在煤岩的分类中，有腐殖煤和腐泥煤之分。本文通过对世界煤成油研究史的考察，指出了腐泥煤不但能生油，而且生成的油能形成煤成油田；但是，迄今为止，还没有发现没有争议的以腐殖煤为主要贡献组分而形成的油田。 In the world, is there an oil field in coal-bearing rocks that is dominated by coal and rock? In the classification of coal and rock, there is humus and sapropelin. Through the investigation of the history of coal-to-oil in the world, this paper points out that saprophytic oil can not only generate oil, but also generate oil that can form coal into oilfields. However, up to now, no controversial humic coal has been found as the main contribution group Divided into the formation of the oil field.
