本文根据不同类型干酪根热模拟的资料,提出生油岩在成熟门限至成油高峰门限阶段的产烃量,Ⅰ类干酸根为14.07%、Ⅱ类为16.50%、Ⅲ类为18.28%,而且绝大部分烃类是进入成油高峰门限后形成的,泌阳凹陷自然剖面成烃规律与上述模拟结果相似,Ⅰ类干酪根从成熟门限至成油高峰阶段,产烃量为15.5%。

On the basis of thermal simulation data of different types of kerogen, the author of this paper proposes the hydrocarbon yields of source rocks during the stage from maturity threshold to peak oil generation, i.e. 14.07% for kerogen Ⅰ, 16.50% for kerogen Ⅱ and 18.28% for kerogen Ⅲ. Most of the hydrocarbons were generated after the stage when peak oil generation have been reached. Taking Bi Well No.08 in Biyang Depression as an example, hydrocarbon generation pattern is fundamentally consistent with the results of thermal simulation mentiond above.
