摘　　要：为解决现有卡瓦在现场使用出现的结构复杂、维修不便、安全性差等问题,研制了一种新型钻杆液压动力卡瓦,它具有刮泥和卡持钻杆的双重功能,可大大提高工作效率;更换不同型号的卡瓦牙,适用于不同直径的钻杆起下钻作业,实现了钻杆液压动力卡瓦的多功能性。该动力卡瓦能与不同转盘规格的自动化液压钻机、配置液压顶驱的钻机及普通钻机配套使用。The new drill pipe hydraulic slip was developed to solve the field problems of complicated structure,uneasy maintenance,poor safety of the available slips used oilfields.The hydraulic slip had functions of scratcher and supporting drillpipes,it could be used to greatly improving the drilling efficiency,when different types of slips were used,it was appropriate for tripping of different drillpipes,it obtained multi-functions in field operation.The hydraulic slip can be used with automatic-hydraulic drilling units with different rotaries,with the drilling units with hydro-top drive and common drilling units.
