摘要
饱和砂岩中扎隙液体的粘滞系数对饱和砂岩的衰减、模量和速度色散的影响在较低频段是明显的。通过对3种不同粘滞系数的液体饱和砂岩的低频共振实验结果表明,随液体的粘滞系数的增大,衰减显著增大,模量增大,存在明显的模量和速度色散,随液体粘性增强,模量与速度色散也有增强的趋势。
The viscosity coefficient of pore fluid in saturated sandstone has an obvious effect on theattenuation, modulus, and velocity dispersion in low frequency range. Low freqency resonance experiments on saturated sandstone with different viscosity coeficient have been performed. The results indicate that the attenuattion, modulus, and velocity dispersion increase with the viscosity coefficient.
