晚白垩系构造抬升降压，使得现今储层为正常—低异常压力。
Structure uplifting in Late Cretaceous made present reservoir pressure be normal-abnormal low.
异常的低孔隙压力可发生于流体已排泄的地区。如一个衰竭的油气储层。
Abnormally low pore pressure might occur in areas where fluids have been drained, such as a depleted hydrocarbon reservoir.
对该凹陷异常压力趋势线进行模拟，找出异常压力高、低值点，根据16口井的资料分析异常压力分布规律，对今后的产能及布井方案提出了建设性意见。
Simulated is the anomaly pressure line to find out high and low pressure points. 16 samples are used here to analyse anomaly pressure's spreading law. Constructive suggestions are proposed for p…
