摘　　要：应用压力平衡原理推导了地层超压与有效埋深的关系,并建立了超压背景下储层孔隙度预测的模型。结果表明,储层中1M Pa的超压相当于埋深减小了41.82m。文中所建立的孔隙度预测模型的精度高于G luyas模型(1997),可用于新区勘探储层孔隙度的预测。The relationship between effective burial depth and overpressure is deduced on the pressure balance principle, and a new model of reservoir porosity prediction is developed. As the result shows,1MPa of overpressure in reservoirs can decrease 41.82m effective burial depth; the precision of our porosity prediction model is higher than that of Gluyas＇ model（1997）. The model developed could be applied to the reservoir porosity predictions of frontier basins.
