COMPOSITIONS OF THE THERMO-DEGRADATIONAL PRODUCTS OF OIL SHALE AND LOW RANK COAL KEROGEN AND THEIR GEOCHEMICAL SIGNIFICANCE

Scientific Research Institute for Petroleum Exploration and Development, Ministry of Petroleum Industry

摘要

摘要: 干酪根作为沉积岩中的主要有机物,在热作用下可裂解成烃,一般认为它是主要的成油母质。由于干酪根的不溶性和相对稳定性,所以它储存了大量可靠的有关母质类型、生源构成、沉积环境等多方面的信息。因此,对干酪根的研究,引起了许多石油勘探工作者和有机地化工作者的普遍注意。

Abstract: This paper deals with the study on kerogen using Py-GC method. Samples were heated to 500℃ rapidly and stayed for 10 minutes. All the thermo-degradational products were collected and analysed on a Varian-3700 Gas Chromatograph. The components determined were classified into normal alkane, normal alkene, isoprenoid alkane, isoprenoid al-kene and alkyl benzenes (naphthalene) and so on. After analyzing and comparing components of thermo-degradational products of two low rank coal kerogens and two oil shales, reliable informations on the composition of precursors, organic type, maturity and sedimentary environment of organic matter in source rocks study are acquired.
