摘　　要：JHQY-B型大功率牵引器由井下控制单元、井下驱动单元和辅助单元等组成,采用混合方式驱动,可根据井下工况要求,自由组合动力模块的数量,形成不同动力等级的牵引器,能更好地适应不同水平井施工要求,与常规牵引器相比,具有牵引力更大及井下环境适应性更强的优点。在江汉油田、重庆涪陵页岩气工区、长庆油田等100多口井的应用结果表明,该牵引器的可控性、携带能力、自适应能力都达到设计要求,能满足长距离复杂水平井作业要求。JHQY--B high--power tractor consists of downhole control unit, downhole driving assembly and auxiliary u- nit. It adopts mixing driving mode. The amount of power modules can be combined according to downhole drilling con- ditions to form tractors with different power grades for different horizontal well construction requirements. Its application in more than 100 wells in areas including Jianghan Oilfield, Chongqing Fuling Shale Gas Workzone and Changqing Oilfield shows that it has reached design requirements in controllability, carrying ability and adaptive ability, thus satisfying long-distance and complicated horizontal well workover conditions.
