摘　　要：地层压力的预测是石油地质研究的重点。利用地震速度谱资料预测地层压力 ,可以有效地指导钻井和其它油气地质研究工作。文章从分析压力预测方法入手 ,认为地震精度、流体性质、断裂、岩性等因素可能导致压力预测结果存在误差。The focus of petroleum research is on the prediction of formation pressure. By using the data of seismic velocity spectrum, formation pressure may be predicted, which can direct the research work of drilling and other explorations. By analyzing the method for predicting formation pressure, the author pointed out in the article that errors could be caused by such factors as seismic precision, fluid quality, fracturing, lithology and so on.
