Design and Construction of a Hydroelectric Drive Coiled Tubing Downhole Tractor

Abstract

This research focuses on the design and development of a novel hydro-electric drive coiled tubing downhole tractor. The tractor consists of upper slips and supports, a trailer structure, a center slip pipe assembly, a control structure, and a lower slips support structure. The unique design of the tractor allows for better control, making it suitable for slim hole well towing operations. Additionally, it ensures normal down-hole liquid circulation, offers flexible bending adaptability, and provides excellent stability. Unlike conventional tractors, this innovative design enables bivector traction, allowing for smooth pulling motion in both directions. Moreover, the tractor incorporates power-off protection to enhance operational safety.
