我国石油地球化学研究和应用方面几个问题的探讨

现今我国所产原油主要来自陆相地层。陆相沉积能够生成石油并形成大规模油气聚集的理论,是我国油气勘探得以迅速发展的一个重要理论基础,而这一理论本身又在实践中不断地得到了发展。

SOME PROBLEMS ON PETROLEUM GEOCHEMICAL RESEARCH AND APPLICATION IN CHINA

The theory of continental petroleum generation in our country has under gone 44 years ever since it has been initiated by Prof.Pan Zhongxiang.In re-cent ten years,much work has been done around the kernel of this theory,i.e.the research and application of petroleum organic geochemistry,and consi-derable advances have been made.On the present state of petroleum organic geochemistry in China,and on the basis of our monograph The Evolution and Hydrocarbon Generation Mechanism of Continental Organic Matter,this paper discusses the following subjects:(1)Classification of kerogen and requirements of high quality oil source areas.(2)The curve and equation of time-temperature relation of petroleum ge-neration threshold.(3)Geochemical significance of low-matured oil.(4)Main functions of relative parameters for biomarkers.(5)The significance of heavy soluble components in rocks during hydro-carbon generation and the limitation of the theory of kerogen-formed oil.(6)Hydrocarbon generation mechanism.
