摘　　要：通过建立不同粒径和泥浆比重的泥浆数理模型,得到了散射衰减系数与泥浆颗粒的直径呈正相关系,衰减系数随着超声波的频率增大而增大。通过研究实际的工程案例,得到了当泥浆粒径小于1.5×10^(-3)时的泥浆物性参数条件下,成孔质量检测效果可以获得较好的信噪比,为工程施工的成孔质量控制提供理论参考。By establishing a slurry mathematical model with different particle sizes and slurry specific gravity,it is obtained that the scattering attenuation coefficient is positively correlated with the diameter of the slurry particles,and the attenuation coefficient increases with the increase of the ultrasonic frequency.By studying the actual engineering case,it is obtained that when the mud particle size is less than 1.5×10^(-3) under the condition of mud physical parameters,the hole quality detection effect can obtain better signal-to-noise ratio,which provides a theoretical reference for the hole quality control of engineering construction.
