| Abstract:Cutting drilling pipe and the assembly with eccentric cutting knife is usually applied in the large diameter engineering borehole construction; and in geological drilling, eccentric cutting knife can used to cut the casing pipe or coring barrel. The paper described a successful treatment practice of complex borehole accident in a drilling construction in Guizhou, the drilling pipe was cut down from the outside with eccentric cutting knife, and introduced the technical measures and the attentions. |
