Description

A kind of tubing string guiding device and adopt the iron driller of this device
Technical field
The present invention relates to a kind of tubing string guiding device, belong to pipe process facility.
The invention still further relates to a kind of iron driller adopting aforementioned tubing string guiding device, in Oil/gas Well drilling, complete button/shackle operation.
Background technology
In Oil/gas Well drilling, when adopting iron driller to carry out upper button/shackle operation, the fixing tube joint cannot aiming at well head is rocked for avoiding pipe, usually by the hand steered pipe of operating personnel (drilling rod, sleeve pipe, drill collar) lead, slow in one's movements, operating efficiency is low, and artificial righting too increases operating risk.
Fig. 1 is existing a kind of tubing string guiding device, is driven the tubaeform block rubber 11 of folding by fluid power push rod 12.When tubaeform block rubber 11 closes up, the guide effect of pipe can be played.
Fig. 2 is the iron driller adopting aforementioned tubing string guiding device.Namely the cylinder body of aforementioned fluid power push rod 12, the fixed end of tubaeform block rubber 11 are arranged on the jaw top of iron driller 10, and the movable end of tubaeform block rubber 11 is connected to the piston rod head of fluid power push rod 12.When the piston rod of fluid power push rod 12 stretches out, the movable end of tubaeform block rubber 11 is drawn close to fixed end and jointly clamps pipe and play guide effect; When the piston rod of fluid power push rod 12 is retracted, the movable end of tubaeform block rubber 11, away from fixed end, unclamps pipe.
But in this tubing string guiding device, the internal diameter of tubaeform block rubber 11 is changeless, when the caliber of clamped pipe is less than the minimum diameter of block rubber 11, just need to change block rubber to adapt to clamped pipe with small pipe diameter; In like manner, pipe with small pipe diameter can block rubber also cannot meet the requirement of righting Large Diameter Pipeline pipe.Therefore, this tubing string guiding device versatility is poor, can not meet the drilling operation having caliber to change demand.Adopt the iron driller of this tubing string guiding device can not meet the demand of fast lifting pipe-handling efficiency.
