Structure uplifting in Late Cretaceous made present reservoir pressure be normal-abnormal low.
晚白垩系构造抬升降压，使得现今储层为正常—低异常压力。

Therefore, caution is needed when using the seismic method to predict the distribution of abnormal pressure in the areas where tectonic uplifting happened in later and recent periods.
在晚近期发生过构造抬升的地区，利用地震法预测异常压力分布需要谨慎。

Based on the principles of physical chemistry, a formula is established for quantitatively calculating formation fluid pressure after tectonic uplifting and erosion in a closed system.
