[0002] Logging bridles are primarily used for the rapid connection of cables and downhole instruments, facilitating the transition from flexible cables to rigid instruments. They possess key characteristics of connectivity, sealing, insulation, and tensile strength. Logging bridles are a crucial link in connecting the surface CNC system, the remote transmission line (logging cable), and the downhole instruments.

[0003] During well logging operations, issues such as damaged cable insulation, cable skipping, and broken wires are frequently encountered, necessitating the fabrication of new logging bridles. However, traditional methods require auxiliary tools such as bench vises and homemade slips. Bench vises are cumbersome and inconvenient to install on logging vehicles. If unexpected situations arise at the construction site, such as damaged cable insulation, skipped wires, broken wires, or twisted wires, it is necessary to return to the base camp to fabricate the logging bridle before returning to the construction site, or to resume construction the next day. This is time-consuming, labor-intensive, delays the construction progress, affects the logging success rate, and seriously impacts oilfield production. Therefore, developing a specialized tool for fabricating logging bridles that is simple in structure, reliable in operation, easy to operate, and portable is an urgent task.
