Background,Motivation and Objective Cement bond quality is significant to productivity and security of a cased wellbore in the oil/gas field. The ultrasonic flexural-wave evaluation is a potential way to detect the debonding which appears at the cement sheath interfaces. In this paper, we present the ultrasonic wavefields in a multilayered cased hole and reveal the flexural wave responses to defects at the cement annulus.
