摘　　要：为了提高原钻杆动力钳的使用效率,在其上增加套管钳功能,实现一钳两用的目的,研制了钻杆套管两用动力钳。该动力钳是在原钻杆动力钳的基础上增加套管动力钳功能。设计了上、下钳间隙调节气缸,使其性能参数能满足钻井及下套管施工需求。在两用动力钳上安装的扭矩控制记录仪,可测量、显示、记录和控制钻杆上扣时扭矩,以保证钻杆、套管上扣时的最佳拧接扭矩。在大庆油田的推广应用中,该动力钳均收到较好的应用效果。由于受结构尺寸的限制,该两用动力钳不适用于大于φ203.2mm的套管。To improve the service efficiency of the original drill pipe power tongs and achieve the dual purposes of the tongs,the dual power tongs for both the drill pipe and casing was developed. The tongs are based on the original drill pipe power tongs with the addition of the function of casing power tongs. The clearance between the upper and lower tongs and the regulation cylinder were designed to make their performance parameter satisfy the operating requirement of drilling and running casing. The torque control recorder was installed on the tongs to measure,display,record and control the torque when the drill pipe screws on and to ensure the optimal screwing torque when the casing screws on. The spread and application in Daqing Oilfield have achieved desirable effects. Due to the constraint of structural dimensions,the tongs are not suitable for the casing with a diameter larger than 203.2 mm.
