【摘要】 为了研究砂岩的应力弛豫衰减随温度和频率的变化规律，笔者在0．1～10HZ的频率范围内进行了饱和砂岩强迫共振试验。实验结果证明：降低温度与增加频率是等效的；砂岩振动的衰减峰随饱和流体的黏滞系数的增加向高温方向移动；黏滞系数和频率对砂岩振动的衰减的影响起相同的作用；随着孔隙率的增大，砂岩振动的衰减也增大。更多还原

【Abstract】 In order to know how stress relaxation attenuation varies with temperature orfrequency,we made a forced resonance experiment on fluid-saturated sandstone inthe frequency range of 0. 1-1OHz. The experiment led to the c0nclusions:. That a decrease in temperature is equivalent to an increase in frequency.. That the attenuation peak of sandstone vibration moves toward high temper-ature direction when the viscosity coefficient of saturation fluid increases.. That viscosity coefficient causes the same influence on vibration attenuationas frequency does.. That higher porosity brings more severe attenuation of sand vibration.更多还原
