等效镜质组反射率及芳烃成熟度参数显示济阳坳陷奥陶系烃源岩大多达到高成熟阶段，部分达到成熟、过成熟阶段。

The equivalent vitrinite reflectance and aromatic maturity parameters showed that most Ordovician source rocks were highly mature, and some of them were mature or over mature.

孔雀河斜坡及邻区发现的油气赋存形式为湿气和凝析油，与现今的高成熟—过成熟的烃源岩不相匹配。

The occurrence shapes of hydrocarbon in Kongquehe slope and its adjacent area are wet gas and condensed oil, which is not in accordance with source rock in high-over maturity period nowadays.
