根据固井质量刻度实验井群的设计要求，介绍了在实验室内制作不同密度、不同声速下地层模拟试块的制作方法，在室内对套管水泥界面质量进行了模拟检测实验，并进行了Ｌａｍｂ波和纵波的测试试验。结果表明，用Ｌａｍｂ波可以检测套管外有无阻尼介质，纵波可以检测套管与水泥环的胶结效果。 According to the design requirements of cementing well scale experimental well group, the making method of formation test blocks in different densities and sound velocities in laboratory was introduced. The simulation test on the interface quality of casing cement was carried out indoors. Lamb wave and longitudinal wave test. The results show that Lamb wave can be used to detect the presence or absence of damping medium outside the casing, longitudinal wave can detect the cementing effect of casing and cementing ring.
