摘要
卡埋钻事故是矿产资源勘查岩心钻探最难处理的事故,传统的强拉、强顶、强扭、反丝钻杆反取等处理方式,处理成功率均极低,且程序繁琐,耗时、耗力、耗成本。为解决卡埋钻事故处理难题,研制了振动拔管器。使用时,将该机具安装在孔口钻杆上,通电即产生高频高压振动,然后用钻机主卷扬向上提拉振动拔管器+钻杆连合体,通过提拔+振动联合作用,实现解除卡阻。振动拔管器坚固耐用、操作方便、成本低廉,在钻探现场应用处理卡埋钻事故数十次,成功率达90%以上,具有极大的推广应用价值。
The stuck drill accident is the most difficult accident to handle in mineral resource exploration core drilling.Traditional methods such as strong pulling,strong jacking,strong twisting,and reverse drilling of drill rods have extremely low success rates,and the program is cumbersome,time-consuming,labor-intensive,and cost-effective.To solve the problem of handling stuck drilling accidents,a vibration pipe extractor has been developed.When in use,the machine is installed on the drill pipe at the orifice,and when powered on,high-frequency and high-voltage vibration is generated.Then,the main winch of the drilling rig is used to pull up the vibration pipe puller+drill pipe combination,and through the combined effect of lifting+vibration,the blockage is relieved.The vibration pipe extractor is sturdy,durable,easy to operate,and cost-effective.It has been applied to deal with dozens of stuck drilling accidents on drilling sites,with a success rate of over 90%,and has significant promotion value.
