Abstract

Abstract

It was concretely introduced an accident of drill bit being buried during the process of large diameter driling without circulation of slurry by hydraulic piling rig.It was analyzed the cause of the accident and the universalities,the importance of the slurry to the techniques was also explored.Some preventive measures and successful methods for treating the accident of drill bit being buried were finally enumerated.
- hydraulic piling rig,
- drilling with non -circulation of slurry,
- drill bit being buried
