摘要
本文主要基于Gassmann方程和经验规律,提出了孔隙流体替代和孔隙度改变时对砂岩地震波速度变化的估计,以及直接利用岩石矿物和孔隙流体的弹性性质计算砂岩地震波速度方法.利用已知的岩芯、测井或地震数据.运用这些方法,可合理地对储层砂岩地震波速度进行预测.
Based on Gassmann's equation and empirical model, wave velocities of sandstones were estimated for pore fluid substitution and porosity change, or calculated by the elastic properties of minerals and pore fluid. With these methods, the seismic wave velocities of reservoir sandstones should be reliably predicted by core, logging and seismic data.
