Abstract
A kind of reparation sucker rod, excise the external screw thread of sucker rod to be repaired, take at the cushion cap that pushes away of sucker rod to be repaired, spanner square neck, the sucker rod screw thread that flange part processing is supporting with the body of rod, it is made to form the reparation body of rod, the sucker rod screw thread repairing the body of rod connects pushing sleeve, the interior stomidium of pushing sleeve is taper seat with the contact-segment of the reparation body of rod, angle between the axis of taper seat and sucker rod screw thread is 6-9o, play a part to lock pushing sleeve, the process of QPQ salt bath is carried out on the body of rod top layer of repairing the body of rod, form QPQ salt bath layer, the reparation body of rod wraps abrasionproof pipe, the sucker rod screw thread made new advances is processed utilizing the structure of former head of sucker rods, the process of QPQ salt bath is carried out on body of rod top layer, form QPQ salt bath layer, add body of rod antifatigue and Corrosion Protection, reach the object that reparation manufactures sucker rod again, therefore, the utility model does not need to drop into new sucker rod manufacturing equipment just can repair sucker rod, the application life of sucker rod can be improved.
Description
Technical field
The utility model is the mechanical device in oil field pumping well, is the sucker rod being connected oil pumping between oil well pump with oil pumper, is a kind of reparation sucker rod.
Background technology
There is the waste and old sucker rod can not gone into the well again in a large number in each oil field, needs to carry out effective reparation and just to go into the well oil pumping.The method of current reparation sucker rod be all generally carry out cleaning, hard surfacing, but there is the little problem of repair coverage in this restorative procedure, to sucker rod pushing away cushion cap, spanner square neck, cannot the repairing of flange part serious wear; Serious cannot the repairing of body of rod surface corrosion.Some restorative procedures forge bar head again after all being removed by the bar head of sucker rod, and this restorative procedure needs to forge equipment, and rehabilitation cost is high; And again forge bar head reparation sucker rod length out can be made to shorten, repeat the heat treatment of the body of rod, increase energy consumption.
Summary of the invention
The purpose of this utility model is a kind of reparation of design sucker rod, makes the box cupling energy eccentric abrasion prevention at its eccentric wear prevention pumping rod two ends, improves the application life of rod string.
The purpose of this utility model is achieved in that the external screw thread excising sucker rod to be repaired, cushion cap shoulder, the processing of spanner square neck, flange part and the supporting sucker rod screw thread of the body of rod is pushed away at sucker rod to be repaired, make it form the reparation body of rod, the sucker rod screw thread repairing the body of rod connects pushing sleeve.
The interior stomidium of pushing sleeve is taper seat with the contact-segment of the reparation body of rod, and the angle between the axis of taper seat and sucker rod screw thread is 6-9o, plays a part to lock pushing sleeve.
The process of QPQ salt bath is carried out on the body of rod top layer of repairing the body of rod, forms QPQ salt bath layer.
The reparation body of rod wraps abrasionproof pipe.
The beneficial effects of the utility model are: process utilizing the structure of former head of sucker rods the sucker rod screw thread made new advances, the process of QPQ salt bath is carried out on body of rod top layer, form QPQ salt bath layer, add body of rod antifatigue and Corrosion Protection, reach the object that reparation manufactures sucker rod again, therefore, the utility model does not need to drop into new sucker rod manufacturing equipment just can repair sucker rod, the application life of sucker rod can be improved, extend the oil well production cycle, reduce workover rig service to oil well cost, improve the economic benefit of pumpingh well.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Embodiment of the present utility model as shown in the figure.Select sucker rod 1 to be repaired, as shown in Figure 1, excise the external screw thread of sucker rod 1 to be repaired, form Fig. 2 structure, push away the supporting sucker rod screw thread 2 of cushion cap shoulder, the processing of spanner square neck, flange part and the body of rod at sucker rod 1 to be repaired, make it be formed and repair the body of rod 3, as shown in Figure 3, the sucker rod screw thread 2 repairing the body of rod 3 connects pushing sleeve 4, generation locking effect when to arrange pushing sleeve 4 be to be connected with box cupling, ensure that the connection between every root sucker rod is reliable, do not produce dropout problem.The interior stomidium of pushing sleeve 4 is taper seat with the contact-segment of the reparation body of rod 3, angle between the axis of taper seat and sucker rod screw thread 2 is 6-9o, make it within the scope of angle of friction, pushing sleeve 4 can produce self-locking with the reparation body of rod 3, play a part to lock pushing sleeve 4, pushing sleeve 4 is reliable with the connection of repairing the body of rod 3, can not loosen.The process of QPQ salt bath is carried out on the body of rod top layer of repairing the body of rod 3, forms QPQ salt bath layer 5, makes it have anticorrosion and anti-fatigue performance.The reparation body of rod 3 wraps abrasionproof pipe 6, increases the abrasion resistance of sucker rod, can application life be improved.As shown in Figure 4.
The screw thread supporting with the body of rod refers to and meets in SY/T5029 " sucker rod ", the thread size that body of rod size is corresponding.
The utility model can arrange erection device at two ends, so that further its anti-wear performance, improves application life.
The utility model can arrange erection device at two ends, so that further its anti-wear performance, improves application life.Also on abrasionproof pipe, application life of the present utility model can be improved by the movable centralizer of suit.
