| 摘 要： | 针对辽河西部凹陷不同岩性、不同干酪根类型18块样品进行了较详细的开放体系生烃动力学研究,模拟结果反映出相同岩性不同有机质类型烃源岩动力学特征存在较大的差异,有机质类型越好,平均活化能越小,主频活化能对应的反应分数越大,活化能分布范围越窄,表明有机质类型对烃源岩生烃动力起着决定性作用.应用平行一级反应模型,结合埋藏史、热史对辽河西部凹陷古近系烃源岩生烃史进行了定量研究,层位上,西部凹陷沙三、沙四段是主力烃源岩,分别占总生烃量的63.9%和18.5%,其次为沙一二段和东营组,4套烃源岩累计生烃量为328.09×108t;东营期是主要的生烃时期.

| Abstract: | The experiments of hydrocarbon-generating dynamics in opening system on 18 samples of different lithology and kerogen types in western depression of Liaohe basin were carried out,and the results show that there exists huge difference between different kerogen types of the same lithology:the better the kerogen types,the lower of the average activity energy;while the larger of the corresponding reaction fraction of dominated frequency activity energy,the narrower distribution range of the activity energy,whic... |
