摘　　要：传统地层孔隙压力的检测方法是基于欠压实机理建立的解释模型;基于有效应力定理,考虑体积压缩系数、有效应力与纵波速度的关系,建立了碳酸盐岩地层孔隙压力的检测模型;利用该模型计算地层孔隙压力,并与实测数据进行对比,符合程度较高;基本解决了传统检测砂泥岩地层孔隙压力的方法不适用于检测碳酸盐岩地层孔隙压力的难题。Traditional method for detecting pore pressure was based on the interpretation model of uncompaction mechanism;on the basis of effective stress law,the relationship between the volume compressibility,the effective stress and compression wave velocity were taken into account to establish a detection model of pore pressure.The model was used to calculate the pore pressure,and compare it with the measured data.The result shows that it has a higher coincidence degree,it can be used to solve difficult problems of traditional methods that are not suitable for detecting pore pressure in carbonate reservoirs.
