Abstract
The utility model discloses a high anti-torque sucker rod, comprising a solid sucker rod body. Two ends of the solid sucker rod body are provided with upsetting structures with the diameters greater than the diameter of the solid sucker rod body, one end of each upsetting structure is provided with a threaded connector, and the part of the threaded connector is provided with a pushing surface. The high anti-torque sucker rod has a simple structure and a reasonable design. Conditions that stress at a friction welded junction is concentrated, and the fracture is easy to occur are overcome, and the reliable guarantee is provided for the improvement of the oil extraction efficiency. In addition, the anti-torque capability of the sucker rod is greatly enhanced, and the sucker rod can bear anti-torque force of relatively high load.
Description
Technical field
The utility model relates to the oil drilling machine technical field, relates in particular to a kind of high torque resistant sucker rod.
Background technology
At present, in the bar producing well was arranged, owing to reasons such as oil pumper stroke, jig frequency and hole conditions, sucker rod will bear bigger axial force in the running up and down.Existing sucker rod is generally the body of rod, bar head, box cupling and is welded as a whole through friction welding, and weld heat-affected zone is little, after the tempered processing of weld seam; Excise inside and outside overlap, and externally overlap carries out rolling and processing, the weld seam bar drawing inspection; Guarantee that weld strength is consistent with the body of rod; But friction weld bond place stress is concentrated, and fracture influences oil recovery efficiency easily.
The utility model content
The utility model provides a kind of simple in structure, reasonable in design to the defective that prior art exists, and can overcome stress and concentrate, and prevents fracture, has improved anti-twisting property, thereby guarantees the high torque resistant sucker rod of oil recovery efficiency.
For solving the problems of the technologies described above; The technical scheme of the utility model is: high torque resistant sucker rod; Comprise the solid sucker rod body of rod; The two ends of the said solid sucker rod body of rod are provided with the jumping-up structure of diameter greater than solid sucker rod body of rod diameter, and an end of said jumping-up structure is provided with nipple, and said threaded joint is arranged with and pushes away bearing surface.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: the utility model is simple in structure, and is reasonable in design, and it has overcome friction weld bond place stress fully concentrates, and the situation of fracture provides reliable guarantee for the raising of oil recovery efficiency easily; And it is used for drive screw pump aspect and strengthens greatly than the anti-twisting property of friction welding type hollow stem, can bear the more twisting resistance of high load capacity.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
The specific embodiment
Shown in accompanying drawing 1; High torque resistant sucker rod comprises the solid sucker rod body of rod 1, and the two ends of the said solid sucker rod body of rod 1 are provided with the jumping-up structure 2 of diameter greater than the solid sucker rod body of rod 1 diameter; One end of said jumping-up structure 2 is provided with nipple 3, and said nipple 3 parts are provided with and push away bearing surface 4.It is to form in the upsetting of solid hopkinson bar two ends, in the bearing surface that pushes away of nipple 3 partial design, to guarantee the reliability that connects and to strengthen its anti-twisting property.
Owing to when nipple 3 is connected with box cupling, is designed with moment of torsion and pushes away bearing surface, increased bar head and box cupling like this and tightened face and get area, can reduce the distortion that pushes away bearing surface, and make torque axis turn to axial pulling force to reduce, reduced the axial load that ridge bears.
High torque resistant sucker rod is compared with the direct-connected hollow stem of friction welding, and it has overcome friction weld bond place stress fully concentrates, and the situation of fracture provides reliable guarantee for the raising of oil recovery efficiency easily; It is used for drive screw pump aspect and strengthens greatly than the anti-twisting property of friction welding type hollow stem, can bear the more twisting resistance of high load capacity.
High torque resistant sucker rod has superpower anti-twisting property because of its special structure design, and anti-twisting property can reach more than the 4000KN.M, therefore is used to drive big screw pump, and obvious effect is arranged.
The utility model is simple in structure, and is reasonable in design, and it has overcome friction weld bond place stress fully concentrates, and the situation of fracture provides reliable guarantee for the raising of oil recovery efficiency easily, and anti-twisting property strengthens greatly, can bear the more twisting resistance of high load capacity.
