“…The maximum normal working temperature of all robot of WWT company can reach 148 °C. The outer diameter of the robot with eccentric link shown in Figure 6 (3) Isotropic dual-slant linkage telescopic drilling traction robot As shown in Figures 7-8, an isotropic dual-slant linkage telescopic drilling traction robot is studied by Zhao [16] et al With two types of support modes, inclined support and linkage support, its maximum traction force of more than 70,000 N. The innovative design method of miniaturization of the eccentric flow channel was also designed [17], resulting in an outer diameter of 100 mm. and found to be working properly.…”

“…The miniaturization of downhole robots is still a pressing issue for the future. The eccentric flow channel proposed by Zhao [17] can reduce the radial size of the robot to achieve the purpose of miniaturization. (3) Large traction As the operating depth and horizontal section length continue to increase, higher demands are placed on the traction force of the traction robot.…”

Coiled tubing (CT) is prone to buckling and locking due to axial friction when extending in large displacement directional wells and horizontal wells. The traction robot of CT can provide axial traction, which can fundamentally address the problem of difficult downward entry of CT. The operation principle, size, traction force, traction speed and other technical indicators of the existing more cutting-edge types of traction robots are analyzed, and the critical structural features of traction robots are summarized. The application prospect of drilling bridge plug technology and drilling technology of the traction robot is put forward. The main points of the research on the traction robot are summarized to provide a concise reference for the future development direction.
