Principles
Combining the pulse echo imaging and the flexural wave imaging, the isolation scanner obtains the inner wall smoothness, the inner diameter, the thickness and the cement bond condition of the casing, and accurately evaluates the cement type from traditional cement paste and heavy cement paste to light cement paste and foamed cement. With its all-directional measurement which covers the circumference of the casing, the scanner is capable of detecting any channels in the cement, so as to confirm the effectiveness of cement job on hydraulic isolation.
