摘　　要：分析了引起地层压力异常的原因,阐述了不同因素引起的压力异常的特征,介绍了测井预测地层压力的等效深度及综合计算2种方法,给出了计算结果与测试结果的对比数据。综述了地震预测地层异常压力的方法以及测井和地震联合预测地层压力的方法。简单介绍了与地层压力预测关系密切的提高地震层速度精度的方法。通过分析地层压力预测技术的现状及存在的问题,阐述了下一步技术研究的重点。The reasons that cause anomalous pore pressures were analyzed. Characteristics of different types of anomalous pressure were documented. Two methods of pore pressure prediction from well logging data were introduced and compared to the results from well test. The techniques for pore pressure prediction from seismic data and from the combination of seismic and well logging were also discussed. Some key issues that should be solved were presented.
