Description
Technical field
The utility model relates to down-hole strings in petroleum industry workover treatment to remove auxiliary device, especially a kind of oil pipe
Elevator, can be general in the workover treatment for having collar oil line and integral joint tubing oil well, and the handling of integral joint tubing can be improved
With remove speed, improve construction efficiency.
Background technique
With the continuous improvement of oil and gas development technique, integral joint tubing using more and more extensive.Integral joint tubing has
Outer diameter is unified, construction unconfined flow generates, the advantage that tensile strength is big.But the characteristics of due to oil pipe without box cupling, needs when playing lower tubular column
To use dedicated taper slips and safety slip coordinative construction.Standing procedure: no hoop oil pipe is clamped on using safety slip
Traditional valve elevator is stuck in safety slip and is drilled into oil pipe thread link position hereinafter, removing by ontology upper end, by taper slips
It is placed in rig floor bushing, integral joint tubing continues to loosen travelling overhead traveling crane for valve under the effect of gravity by taper slips locking
Elevator and safety slip are detached from, and open valve elevator, and safety slip of dismantling carries out the dismounting construction without hoop oil pipe.Tradition is done
Method large labor intensity, construction efficiency are low.
Well workover construction site needs to invent a kind of elevator that can be universally used in box cupling and integral joint tubing, and well workover is facilitated to apply
Work.
Summary of the invention
The purpose of the utility model is to provide a kind of pipe elevators, use oil pipe in present apparatus auxiliary workover operation construction
It removes, enables have collar oil line normal use, integral joint tubing is also able to use.Facilitate workover operation construction, reduce worker
Labor intensity, improve construction efficiency.
Purpose of the utility model is realized as follows: a kind of pipe elevator includes ontology, valve and handle, ontology and work
Assembly side between door is connected by shaft, and the open side between ontology and valve is by being somebody's turn to do loaded on the lock pin locking in valve
Lock pin is connected by linkage mechanism with handle, and slips is housed in the center bore inner wall that ontology and valve are formed.
Compared with prior art, the significant using effect of the utility model is: the present apparatus can have collar oil line and nothing
It is general in the workover rig service to oil well of collar oil line.As long as not installation card watt, there is collar oil line to use end face upward ontology
It is able to cooperate the workover treatment of collar oil line；As long as by ontology without box cupling using end face upward, in no box cupling use end face
It is packed into slips in centre bore, is just able to cooperate the workover treatment of integral joint tubing.The utility model substantially increases operating efficiency, shows
The labor intensity for reducing worker is write, there is significant using effect, and apparent economic benefit can be generated.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing, not limits the protection scope of the utility model.It is as described below to be only
The preferred embodiment of the utility model, other use the equivalence changes of the utility model, should belong to the protection of the utility model
Range.
Referring to Fig. 1, a kind of pipe elevator includes ontology 1, valve 4 and handle 9, and the assembly side between ontology 1 and valve 4 is logical
The connection of shaft 7 is crossed, the open side between ontology 1 and valve 4 passes through loaded on 8 locking of lock pin in valve 4, the lock pin 8 and handle 9
It is connected by linkage mechanism, slips 5 is housed in the center bore inner wall that ontology 1 and valve 4 are formed.
It is equipped with slips mounting groove in one end inner wall of 4 centre bore of the ontology 1 and valve, which is and this
Body 1 and valve 4 are formed by centre bore vertical slot in the same direction.
The medial surface of the slips 5 is the arc conical surface, on the arc conical surface be equipped with slip insert, the tooth form of slip insert be to
Inclined unidirectional tooth；The small big, minimum-value aperture of centre bore that is formed by slips 5 under the aperture of the centre bore formed by slips 5
Less than the outer diameter of integral joint tubing, it can make to be stuck in integral joint tubing therein and be locked naturally under tube body self weight.
The slips mounting groove that the slips 5 installed in the ontology 1 and valve 4 is correspondingly arranged at least provided with three pieces and slips 5
At least provided with three, slips 5 is fixed in the slips mounting groove of ontology 1 and valve 4 by slips fixing screws 6.
The end face that 5 one end of slips is mounted in the ontology 1 is integral joint tubing using end face 2, is used for integral joint tubing
Well workover construction, when use places the end face upward.
The end face that 5 one end of slips is fitted without in the ontology 1 is that have collar oil line using end face 3, for there is box cupling oily
The well workover of pipe is constructed, and when use places the end face upward.
In use, if operating tool string is to have a collar oil line, the present apparatus is had box cupling oily by not installation card watt 5 in the present apparatus
Pipe is placed upward using end face 3, and the tubing coupling for having collar oil line is transferred to the top of the present apparatus, is pulled valve handle 9, is beaten
Valve 4 is opened, valve 4 is fully opened.Ontology 1 is stuck in the lower section of tubing coupling, closes valve 4, tubing coupling is supported on
Ontology 1 has collar oil line using above end face 3, can be attached or dismantle the workover operation construction of oil pipe.It connects or tears open
After the operation of oil discharge pipe, upper lifting pipe post pulls valve handle 9 again, opens valve 4, fully opens valve 4, this is filled
Oil pipe in setting takes out, and completes single construction.
If operating tool string is integral joint tubing, the integral joint tubing of the present apparatus is placed upward using end face 2, by slips 5
It is placed in the slips mounting groove of ontology 1 and valve 4, is fixed by slips fixed pin holes screw 6.It will be under integral joint tubing
It is put into the position that oil pipe ontology needs to block, handle 9 is pulled, opens valve 4, fully open valve 4, ontology 1 is stuck in nothing
Outside the tube body of collar oil line；Valve 4 is closed, transfers integral joint tubing, integral joint tubing is under ontology gravity, by slips
It 5 lockings and the more embraces the more tight, can be attached or dismantle the workover operation construction of oil pipe.Connection or disassembly tubing manipulation terminate
Afterwards, upper lifting pipe post pulls handle 9 again, opens valve 4, fully opens valve 4, and the oil pipe in the present apparatus is taken out, and completes
Single construction.
The embodiment described above is only exemplary embodiments, but the utility model is not limited only to these embodiments, ability
The technical staff in domain can make modification under the spirit and enlightenment without departing from the utility model.Aspect disclosed herein may
In the presence of many changes, combination and modification, and all in the scope of the utility model, therefore, protection scope is not limited only to above
Explanation.
