近年来,在石油成因的研究中,晚期成油学说已越来越为广大石油工作者所承认,并为勘探和实验的实践逐步证实。该学说的要点是:有机质堆积后,经生化阶段逐渐形成干酪根(Kerogen)即油母质(不溶有机物总称)。干酪根是一种网状结构的高分子聚合物,由环烷烃、芳香烃(间有杂环和脂肪链族)缩聚而成。 In recent years, in the study of oil genesis, the theory of late oil production has been recognized by the majority of oil workers more and more and confirmed gradually by the practice of exploration and experiment. The key point of this doctrine is that Kerogen, the kerogen (collectively referred to as Insoluble Organics), is gradually formed through biochemical stages after the accumulation of organic matter. Kerogen is a network of high molecular polymers, from naphthene, aromatic hydrocarbons (between heterocyclic and aliphatic chain) polycondensation.
