Description
A-One Oil Memory Cement Bond Logging Tool is primarily used to evaluate the cement bond between the casing and the formation, providing key indicators for assessing the sealing integrity of oil, gas, and water wells.
The MCBL includes a 3-foot sector receiving probe, and a 5-foot VDL (Variable Density Log) probe. Each sector covers a 45° cross-section, allowing for a 360° assessment of the cement bond integrity.

Features
◆ Memory Cement Bond Logging Tool 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.
◆ Adapting the ultrasonic probe heads are structured in an independent design, offering strong reliability and convenient maintenance.
◆ Adding the unique-designed with roller centralizer, complemented by upper and lower roller centralizers, making it particularly suitable for well logging in high-angle and horizontal wells where oil pipes or drill pipes are used as the conveyance method.
◆ Owning the large-capacity storage system, high-speed data acquisition frequency, and ultra-fast data reading speed, enabling refined and rapid well logging.
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.
◆ Meet the requirements for well logging in casings ranging from 4.5 in (114mm) to 10 in (254mm).
◆ Quantitatively evaluate the bond index of the first interface, and qualitatively assess the bond index of the second interface.
FAQ
Q: Can Memory Cement Bond Logging Tool be used for joint logging with an electromagnetic thickness – EMFD43C and a Multi - Arm Caliper Logging Tool?
