Abstract

Abstract

In drilling engineering the drop and the deviation of the drilling stem are the common accidents which are difficult to deal with. If the skew torlerance is too large to deviate from the design depth position, and the skew direction is difficult to judge, at the same time the drilling stem is possibly in the working area of TBM(Tunnel Boring Machine). This special case requires us to determine the specific skew position, once the drilling stem has deviated to the working area of TBM,we have to remove the drilling stem by all means.
