摘要

摘要: 烃源岩活化能分析表明,源岩活化能与R_o和镜质组含量存在正相关关系;与腐泥组关系有2种趋势,当组分未受到微生物强烈改造时表现出负相关,反之为正相关;活化能与壳质组含量的关系表现为随壳质组含量增加而降低的趋势。研究还表明烃源岩生烃活化能受到多种因素的影响,其生烃机制是复杂的。藻类物质具有早期生烃的特点,是未熟—低熟油的重要烃源,而具有多类显微组分的烃源岩有多期生烃的特性。

Abstract: The distributions of activation energy of different hydrocarbon source rocks and the relationship between average activation energy and different macerals were discussed in this paper.Research results show that a positive correlation between maturity and average activation energy can be observed.The same is true of the content of vitrinite.The correlation between the content of lipinite and average activation energy have two kinds of trend.It is a positive correlation when the organic matters have been altered strongly by microbe,if not,there is a negative correlation.The correlation between the content of exinite and average activation energy shows a negative trend.The research confirms that activation energy of hydrocarbon source rock has many influential factors and its hydrocarbon generation principle is complicated.Algae have characteristics of inchoate hydrocarbon generation and they are important hydrocarbon sources of immature oil.The hydrocarbon source rocks which possess many kinds of maceral have characteristics of multi-period hydrocarbon generation.
