运用含油气系统理论的盆地模拟技术,对鹿邑改造型复合盆地含油气系统动态地质作用进行了模拟分析。认为鹿邑凹陷石炭-二叠系具备二次生烃的有利条件,烃源岩经历了燕山和喜山两次生烃高峰期,喜山期是油气成藏的关键时期,同时指出了勘探的主攻方向。

 Using the basin modeling technology based on the method of petroleum system, Aut hors have simulated and analyzed the dynamic geological process of petroleum sys tem in Luyi depression which was composite and reconstructed. There are favorabl e conditions of secondary generating hydrocarbon to Carboniferous-Permian resou rce rocks in Luyi depression. The hydrocarbon resource rocks had passed through  the two fastigiums of generating hydrocarbon, which are Yenshan period and Himal ayan period. The key period of accumulation is Himalayan period. In the end, the  exploring targets have been predicted.
