摘　　要：干酪根热降解生油学说源于油页岩高温热解生成“人造石油”的生产实践,其理论内涵是凡富含干酪根的岩石,经高温热解后其所含的干酪根都可以生成“人造石油”。应用该学说的高温热解实验方法,可以评价油页岩的品质及其热解生成“人造石油”的潜力,因此仅适用于油页岩的评价研究。但该学说的倡导者却认为油页岩和油源岩都是能生成石油的岩石,如果埋藏较浅时就称为油页岩,如果埋藏较深时就是油源岩,因此干酪根热降解生油学说同样适用于油源岩。这种观点并没有被美欧等国家所认可,但遗憾的是,在改革开放之初不甚了解国外同行对该学说如何评价的情况下,中国的石油地质家不仅全盘接受了该学说,而且推广应用了40多年。为彻底改变这种被动局面,唯一可行的就是通过油源岩沉积成岩成油模拟实验,研究油源岩中可溶有机质的生油问题和评价方法。The theory of oil generation from kerogen thermal degradation originates from the production prac-tice of "artificial petroleum" generated by high-temperature pyrolysis of oil shale.Its theoretical connotation is that the kerogen in the rocks can generate "artificial petroleum" after pyrolysis of the kerogen-rich rocks.The application of the pyrolysis experimental method of this theory can be used to evaluate the quality of oil shale and its potential to generate "artificial petroleum" through pyrolysis,so it is only suitable for the evaluation research of oil shale.However,the advocates of this theory believe that oil shale and oil source rock are both oil-generating rocks.If buried shallowly,it is called oil shale;and if buried deeply,it is oil source rock.Therefore,the theory of oil generation through kerogen thermal degradation is also applicable to oil source rocks.This viewpoint has not been recognized by the United States,Europe,and other countries.Unfortunately,at the beginning of the reform and opening up,without knowing much about how foreign peers evaluate this theory,Chinese petroleum geologists not only accepted this theory in full but also promoted and applied it for more than 40 years.To completely change this passive situation,the only feasible way is to study the oil generation and evaluation methods of soluble organic matter in source rocks through the simulation experiments of sedimentary diagenesis and oil generation of oil source rocks.
