从异常地层压力的成因机制出发,建立了一种以测井资料为约束条件,利用地震反演技术的地层压力预测方法，其流程包括：①通过不同孔隙度测井曲线的综合比对,再结合地质综合分析,确定研究区地层压力与孔隙度有关；②在满足适用条件的前提下,从多井的测井声波曲线中提取正常变化趋势和地表声波值等参数,绘制平面图来约束预测参数的平面变化；③以测井声波曲线为约束,对三维地震数据体进行速度体反演,保证速度体空间变化的客观性；④以平衡深度法将速度体转化为所需压力数据体。该方法综合了测井资料纵向分辨率高、对区域特点反映强和地震资料空间连续性好的特点，适用于以不均衡压实作用为增压机制和与孔隙度异常有关的地层压力预测。在我国东部新生代盆地的应用显示,压力预测结果符合率高,误差小,对地层压力展布和结构反映清晰,效果良好。

The formation pressure prediction with well constrained seismic inversion data can be applied to abnormal porosity formations in which abnormal pressures derive from disequilibrium compaction action. Firstly, identify the mechanisms of abnormal pressure and make sure that it is related to disequilibrium. Secondly, map the normal trend distribution of sonic velocity and velocity on surface using sonic log data. Both of them are the important parameters in this method. Thirdly, extract bed velocity body with well constrained seismic inversion. After that, formation pressure can be calculated by balance depth equation.
