摘要： 通过渤海湾盆地渤中凹陷古近系的测压、测井数据建立全井段地层压力曲线，划分其垂向超压带，并根据垂直有效应力-速度交会图、烃源岩发育层段及镜质体反射率分析了超压成因和类型，完善了超压成因的识别方法。研究结果表明：①渤中凹陷古近系东二下段至沙三段均发育异常超压，超压成因主要为欠压实、有机质生烃、流体传导，随着地层年代变老，超压成因由欠压实向有机质生烃、流体传导等非欠压实成因变化。②欠压实超压多发生在厚泥岩段，声波速度变化小，岩石密度较小，垂直有效应力稳定；有机质生烃超压层段的声波速度低于正常压实地层的速度，但随深度增加略有增大，垂直有效应力较小；流体传导超压一般发生于不具备自源型超压生成条件的流体封存箱，声波速度及岩石密度均为正常压实趋势，实测压力纵向上随深度线性增加，表现为同一压力系统。

关键词: 欠压实超压, 有机质生烃超压, 流体传导超压, 地层超压成因, 测井响应特征, 古近系, 渤中凹陷, 渤海湾盆地

Abstract: Based on pressure measurement and logging data of Paleogene in Bozhong Sag，Bohai Bay Basin， the formation pressure curves of the whole well section were established，and the vertical overpressure zones were divided. The genesis and types of overpressure were analyzed by the consideration of vertical effective stress-velocity cross plot，source rock development and vitrinite reflectance，and the method for identifying overpressure was improved. The results show that： （1）Abnormal overpressure developed in the lower second member of Dongying Formation and the third member of Shahejie Formation of Paleogene in Bozhong Sag. The genesis of overpressure is mainly undercompaction，hydrocarbon generation of organic matter and fluid conduction， with the aging of the strata，the overpressure genesis changes from undercompaction to non-undercompaction such as hydrocarbon generation of organic matter and fluid conduction.（2）The overpressure caused by undercompaction generally corresponds to thick mudstone section，with little change of acoustic velocity，low rock density and stable vertical effective stress. The overpressure caused by hydrocarbon generation of organic matter corresponds to the strata with acoustic velocity being lower than that of normal compacted strata，but it increases slightly with the increase of depth，and the vertical effective stress is low. The overpressure caused by fluid conduction generally occurs in overpressure fluid compartments without the conditions for self-source overpressure generation，the acoustic velocity and rock density show normal compaction trend，and the measured pressure increases linearly with depth in the longitudinal direction， showing the same pressure system.

Key words: undercompaction overpressure, overpressure caused by hydrocarbon generation of organic matter, fluid conduction overpressure, genesis of formation overpressure, logging response characteristics, Paleogene, Bozhong Sag, Bohai Bay Basin
