岩心钻探振动拔管器的研制及在卡埋钻处理中的应用
Development of vibration pipe puller and its application in dealing with stuck and buried drilling in core drilling
摘要
Abstract
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.关键词
