Thickness reversion method of water layer from one dimension reflective data in ultrasonic reflective cement bond logging is theoretically studied when the first interface is bad bonded.
针对单道超声反射式水泥胶结测井，从理论方法上研究如何从一维反射资料反演第一界面窜槽时水层的厚度。

This method can be used for ultrasonic NDT in a multilayered medium, for example cement bond log.
这种方法能用于多层介质中超声无损检测。
