从包体测温和镜质体反演资料推测平北工区经历了高于今地温梯度的热历史，这对平湖组烃源岩或深部烃源岩演化有利。
From inclusion and ro data, it is clear that Pingbei strata had undergone a higher temperature gradient in geological history, which is favorable for source rock evolution.
但由于生油层埋藏较浅，地温梯度偏低，致使各生油层有机质的成熟度明显比好生油凹陷低，主要生油层目前仍处于低成熟—成熟演化阶段。
But the level of maturity of organic matter in the source rocks is obviously lower, because the lower tertiary source beds are of shallower burial and smaller geothermal gradient.
