摘要
燕山地区洪水庄组发育高有机质丰度的黑色页岩。利用开放体系程序升温热模拟试验结果表明,洪水庄组烃源岩有机质热裂解反应主要发生在400~480℃之间,其表观生烃活化能集中分布在40~70kcal/mol之间,平均为54.47kcal/mol,其活化能分布与典型Ⅱ型有机质（法国巴黎盆地Toarcian页岩）活化能分布极为相似,可能具有相似的生烃机理,这也许与元古界生物种属简单、生物分异程度小有关;地质条件下,洪水庄组烃源岩有机质主生烃期温度范围在117~162℃（Ro为0.68%~1.19%）,表现出生烃时间较早、生烃集中的特点。
Hongshuizhuang Formation developed high organic black shales.The results indicate the thermal cracking reaction of organic matter from Hongshuizhuang Formation is induced between 400～480℃.The distribution of apparent hydrocarbon generation activation energy is mainly ranged from 40 to 70 kcal/mol with the average of 54.47 kcal/mol,which is similar with the typical organic matter of type Ⅱorganic matter(such as Toarcian shales from Paris Basin,France).So they possibly has the semblable the mechanism of generation,which is related with the simple organisms and the low degree of organism differentiation.Under the geological conditions,the main hydrocarbon generation temperature of organic matter in Hongshuizhuang Formation is 117～162℃(i.e.Ro ranged from 0.68% to 1.19%),which indicates the character of early time and concentration of hydrocarbon generation.
