The clogging caused by the deposition of suspended particles modifies in depth several mechanical parameters (permeability, porosity, bulk moduli, etc.) of porous media and influences the acoustic behaviour. Consequently, at a fixed position in the medium, changes in phase velocity and attenuation are observed in the amplitude of the temporal signal of the transmitted waves. In this work, ultrasonic techniques are presented both for detecting and measuring the clogging in a water saturated porous medium. The acoustic measurements from the clogged samples are compared with the deposition profiles obtained at the end of injection experiments. Moreover, links are established between on the one hand phase velocity and the total porosity, and on the other hand the transmitted signal energy and the variation of porosity as consequence of particle deposition.

堵塞对饱和颗粒单孔和双孔介质超声传输的影响

由悬浮颗粒沉积引起的堵塞会在深度上改变多孔介质的几个机械参数(渗透率、孔隙率、体积模量等)并影响声学行为。因此,在介质中的固定位置,在传输波的时间信号的幅度中观察到相速度和衰减的变化。在这项工作中,提出了超声波技术,用于检测和测量水饱和多孔介质中的堵塞。将堵塞样品的声学测量结果与注射实验结束时获得的沉积分布图进行比较。此外,一方面在相速度和总孔隙度之间建立了联系,
