The structure of the direct-drive TDS eliminates the need for a gearbox and lubrication system compared with other ordinary TDS, which realizes the machine and electron inter-coupling. The application on site indicated that it could increase continuous operation torque,enhance the TDS capability of resolving emergency in well drilling process,and reduce the failure rate and maintenance labor intensity and time. It has very good reliability,economy and the popularization foreground in drilling rig.%介绍了一种利用机电融合技术设计出的新型顶驱——直驱式顶驱装置.该顶驱装置采用大功率交流变频电动机直接驱动主轴,与传统的顶驱相比取消了机械变速机构,实现了电机与机械的相互融合.国外现场使用情况表明:与传统同型号的顶驱相比,不仅明显提高连续钻井作业扭矩,并且显著降低设备使用故障率与维护强度,增强了应对钻井事故的能力.具有较强的可靠性、经济性和良好的推广前景.
