Abstract: Disclosed are a wellbore inspection system and method for an ultra-deep vertical shaft. The wellbore inspection system includes a wire rope moving system, inspection robots, a visual image acquisition system, a wireless communication module, a central control system, and an image post-processing system of an upper computer. The wire rope moving system includes a surface wire rope guide rail, an underground wire rope guide rail, a surface wire rope moving device, an underground wire rope moving device, and a wire rope. The visual image acquisition system includes explosion-proof cameras. After image information acquired by the explosion-proof cameras is processed by a lower computer, the processed image is transmitted by a wireless image transmission module to the image post-processing system of the upper computer. The central control system is connected to the inspection robots and the wire rope moving system, and the inspection robots are connected to the central control system.

Abstract: A movement-synchronized wellbore inspection system and a movement-synchronization control method thereof are disclosed. The wellbore inspection system comprises a rope-climbing robot, a wire rope, a ground wire rope moving device, a ground wire rope moving track, an underground wire rope moving device, an underground wire rope moving track, an inertial sensor and a control device. An upper end of the wire rope is connected to the ground wire rope moving device, and an lower end of the wire rope passes through the rope-climbing robot and is then connected to the underground wire rope moving device. The control device controls the underground and ground wire rope moving devices to move in synchronization, and then the inertial sensor carried on the rope-climbing robot detects posture data of the wire rope and transmits the data to the control device.
