中国低熟油的几种成因机制

在对国内外文献详尽检索研究基础上，根据对国内９个二级沉积凹陷和５个中、小型盆地的有机地球化学、有机岩石学和同位素地球化学的系统研究，作者建立了木栓质体、树脂体、细菌改造的陆源有机质、藻类与高等植物生物类脂物以及富硫大分子（非烃、沥青质和干酪根）等五种早期生烃形成低熟油的成因机制。

Several Genetic Mechanisms of Immature Crude Oils in China

Based on a detailed literature investigation into the generation and occurrence of Chinese and inter-national immature crude oils, the authors selected 9 Tertary sedimentary sags as typical cuses for system-atic analysis and study in combination with the comparative study of typical crude oils and source rocksfrom 5 M eso Cenozoic medium to small size sedimentary basins in China, totally 102 wells and relatedsurface or coal mine sections were involved and 33 oil and 563 rock samples were collected f o r o rganicgeocheen cal, organic petrological and isotopic geocheen cal analyses, altogether 24 different analyticaltechniques were used and plentiful experimental data were obtained, in the basis of which, 5 geneticmechanisms of early generation for immature crude oils, i. e.,hydrocarbons derived from subrinite, resi-nite, bacteria-reworked terrestrial organic metter, algal and higher plant biolipids as well as sulfur-rchromolecules(such as non}ydrocarbons,asphaltenes and Typell kerogen),were proposed.
