摘　　要：井下牵引器能够在深井、超深井、大斜度井以及大位移水平井中输送测井仪器或井下工具到井下需求的位置,并为其提供电能与通讯。文章介绍了几种不同类型的井下牵引器国内外主流产品的结构特点、技术指标以及应用情况;并结合目前钻完井工艺技术发展的需求,提出了具有大尺寸、大牵引力、高速度、越障及自动解卡能力的井下牵引器的发展方向和研究建议。Downhole tractors, used in deep wells, ultra - deep wells, high angle wells and horizontal wells with large displacement, can convey logging instruments or tools to the position of downhole for requirements, and provide them with power and communication. This article introduces the development of some domestic and foreign downhole tractors for horizontal wells, including the structure, working principle and performance parameters. Combining with the present development of drilling and completion technology, the article proposes the idea for the design and development of downhole tractors for horizontal wells,with large size, big traction and high speed.
