基于BLBL模型的超声波在钻井液中的传播衰减规律
Study on Attenuation Law of Ultrasonic Wave in Drilling Fluid Based on BLBL Model
摘要
Abstract
Based on BLBL acoustic attenuation model,the propagation and attenuation law of ultrasound in drilling fluids with different properties was studied using numerical simulation software MATLAB.The research results indicate that an increase in ultrasonic fre-quency will intensify the attenuation of ultrasonic waves in drilling fluids,with the attenuation first slow and then fast,and the higher the frequency,the faster the rate of the attenuation.Meanwhile,the increase in drilling fluid viscosity,temperature and density all leads to an increase in the attenuation degree of ultrasonic waves.The orthogonal experimental results indicate that the order of influence of the four factors on ultrasonic attenuation,from large to small,is:drilling fluid viscosity,drilling fluid temperature,ultrasonic frequency,and drill-ing fluid density.The research results provide theoretical support and guidance for the application of ultrasound in drilling fluid meas-urement.关键词
