RJ-500型柔杆钻机阶段性成果鉴定会于1981年4月16日至21日在广州加禾召开.到会代表来自全国煤炭、冶金、地质、石油、铁道、电器、机械等生产部门、科研和大专院校共33个单位,67人. 柔杆钻机是当前国内、外一种新型的钻探设备,其主要特点是用连续的柔性钻杆代替刚性的一根一根的钻杆,井下电机在井底直接驱动钻具进行钻进,这样就大大的节省了钻进过程中的起、下钻具时间,不仅提高了动力利用率,而且提高了钻进效率和钻孔
The identification of the stage achievements of the RJ-500 flexible rod drilling rig will be held in Jiahe, Guangzhou from April 16 to April 21, 1981. The representatives from the coal, metallurgy, geology, petroleum, railway, electrical appliances and machinery production departments, Scientific research and tertiary institutions a total of 33 units, 67. Flexible rod rig is currently a new type of domestic and foreign drilling equipment, its main feature is the use of continuous flexible drill pipe instead of a rigid one of the drill pipe, downhole The motor directly drives the drilling tool to drill at the bottom of the well, thus greatly saving the time of drilling and drilling tools during the drilling process, not only improving the power utilization rate, but also improving the drilling efficiency and drilling
