通过改变流体的粘滞系数研究饱和流体砂岩的衰减及模量色散,探讨衰减与激发频率、共振振幅的关系,比较砂岩中不同饱和流体时衰减的变化.并采用滞弹性固体三参数模型和cole-cole分布来解释所观测到的实验现象.
The attenuation and modal dispersion of saturated fluid sandstone are studied by changing the fluid viscosity coefficient. The relationship between attenuation and excitation frequency and resonant amplitude is discussed. The attenuation of different saturated fluids in sandstone is compared. The anelastic elastic three-parameter model and the cole-cole distribution are used to explain the experimental phenomena observed.
