摘　　要：研制的JC-15D绞车主要由绞车架、滚筒轴、320 kW电动机、液压盘式刹车、电气控制系统和润滑系统等组成。该绞车采用主电动机直接驱动滚筒轴,整个变速过程完全由主电动机交流变频控制系统操作实现,具有提升和下放钻具、取心和处理事故等功能;主电机还可实现恒钻速或恒钻压自动送钻,主刹车采用主电动机能耗制动,辅助刹车采用液压盘式刹车。试验情况表明,在井架上段的起升和下放及正常钻井过程中绞车运行平稳,润滑充分,密封及连接可靠;主电动机连续调速、能耗制动减速及零速悬停功能良好,主电动机恒钻压(恒钻速)自动送钻速度和扭矩能满足钻井工艺要求;滚筒缠绳整齐有序;液压辅助刹车灵敏可靠。截止到2011年7月5日,JC-15D绞车已无故障累计运行700 h。The JC -15D drawworks developed mainly consists of jack frame, drum shaft, 320 kW motor, hydraulic disc brake, electric control system and lubrication system. The motor transmits power to the drum shaft through the coupling in a synchronous way. The overall variable speed process of the drawworks is completely achieved by the AC variable frequency control system. The advanced low-speed high-torque permanent magnet motor is adopted to drive the drum shaft directly. As a result, the drawworks structure is simplified remarkably and its mass is reduced, the transmission efficiency is improved, and the precise control of super-low speed continuously variable transmission is achieved. The field application has reached desirable efthcts.
