Description
A-One Oil Cement Bond Tools mainly used to detect the cementing quality of casing wells. The CBT includes a 3-foot sector receiving probe, and a 5-foot VDL (Variable Density Log) probe. Each sector covers a 45-degree cross-section, allowing for a 360° assessment of the cement bond integrity. It is one of the more advanced methods currently used in cement bond logging both domestic and overseas.

Features
◆ Cement Bond Tools adapting the 13-core quick connector design, which facilitates easy connection with multi-arm, electromagnetic flaw detection, downhole television, and other instruments, enhancing the efficiency of correlative well logging data acquisition.
◆ 360° evaluation: Each sector covers a 45° section, ensuring comprehensive evaluation of bonding integrity.
Applications
◆ Perform well logging in operations where cable provision is not possible.
◆ Provide a 360° cement bond log (CBL) image.
◆ Measure the quality of cement bonding in both horizontal and conventional wells.
◆ Quantitatively evaluate the bond index of the first interface, and qualitatively assess the bond index of the second interface.
FAQ
