Abstract
The utility model belongs to a power transfer device in a sucker-rod pump of an oil field. A novel upsetting type tripping proof and solid oil suction rod is designed in order to prevent the generation of the accident of the tripping of an oil suction rod. The utility model is composed of a joint 1 on the lower part of a rod body, a coupling 2, a joint 3 on the upper part of the rod body and a rod body 4. A sector tooth body on the lower end of the joint 1 on the lower part of the rod body and the sector tooth body of the upper end of the joint 3 on the upper part of the rod body are embedded, connected and cooperated. The utility model can effectively prevent the accident generation of the tripping of the oil suction rod, and save operational cost, and the utility model is especially suitable for being used in a screw pump well.
Description
The utility model belongs to the power transmission in the rod pumped well of oil field.
Solid sucker rod is mainly used in rod-pumped well and the screw bolt well when pumping crude oil, and power is passed to the down-hole by ground, drives the rotation of plunger upward and downward or drive screw pump rotor, reaches the purpose of final pumping crude oil.Present existing upset forging type solid sucker rod, as shown in Figure 5, the connection of two ends up and down of this upset forging type solid sucker rod is external screw thread and connects, it mainly by body of rod bottom joint 1 ', box cupling 2 ', body of rod top sub 3 ' and the body of rod 4 ' form, body of rod bottom joint 1 ', body of rod top sub 3 ' and the body of rod 4 ' be the one upset forging type, box cupling 2 ' up and down and body of rod bottom joint 1 ', body of rod top sub 3 ' between all by screwed connection.Though the connected mode of this upset forging type solid sucker rod can satisfy the transmission demand of rod-pumped well and screw bolt well medium power at present, but the rod-pumped well body of rod move up and down for a long time and screw bolt well in body of rod when rotation, all can cause the box cupling 2 of this sucker rod ' and body of rod bottom joint 1 ' and body of rod top sub 3 ' between the screwed connection position take place loosening, thereby cause the dropout accident.
The purpose of this utility model provides a kind of novel upset forging type anti-loosing solid pumping rod that prevents that in the down-hole dropout accident takes place between the sucker rod.
The purpose of this utility model can reach by following measure:
This upset forging type anti-loosing solid pumping rod is made up of body of rod bottom joint, box cupling, body of rod top sub and the body of rod.Body of rod bottom joint wherein, the body of rod top sub and the body of rod are the one upset forging types, the lower end of body of rod bottom joint is two sectorial teeth bodies that certain angle is arranged, the upper end of body of rod top sub also is two sectorial teeth bodies that certain angle is arranged, the size of two tooth bodies and structure can make both successfully embed and be connected, box cupling inner with embedded the body of rod bottom joint that is connected, all be threaded between the body of rod top sub, joint sectorial teeth body top, body of rod bottom does not have shoulder, shoulder is arranged at the sectorial teeth body bottom of body of rod top sub, when box cupling is tightened downwards, lock and be positioned on the shoulder of body of rod top sub.
Preferably 45 ° of angles between two sectorial teeth bodies of body of rod top sub upper end and joint lower end, body of rod bottom are because the sectorial teeth body realization equal strength of body of rod top sub and body of rod bottom joint at this moment.
Body of rod top sub upper end can also be regular polygon or non-regular polygon with the shape of cross section of two tooth bodies of joint lower end, body of rod bottom, is connected but polygonal design should make both embed smoothly.
Compared with the prior art the utility model has following advantage:
1, has functions such as the rod string of preventing dropout, be particularly useful for screw bolt well.
2, can reduce the operation number of times, save operating cost.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is a body of rod top sub sectorial teeth body A-A cross-sectional view;
Fig. 3 is the utility model B-B cross-sectional view;
Fig. 4 is a body of rod bottom joint sectorial teeth body C-C cross-sectional view;
Fig. 5 is existing upset forging type solid sucker rod structure diagram.
Below in conjunction with accompanying drawing the utility model is done further auspicious stating:
This upset forging type anti-loosing solid pumping rod is made up of body of rod bottom joint 1, box cupling 2, body of rod top sub 3 and the body of rod 4.Body of rod bottom joint 1 wherein, the body of rod top sub 3 and the body of rod 4 are one upset forging types, the lower end of body of rod bottom joint 1 is two sectorial teeth bodies that certain angle is arranged, the upper end of body of rod top sub 3 also is two sectorial teeth bodies that certain angle is arranged, the size of two tooth bodies and structure can make both successfully embed and be connected, box cupling 2 inner with embedded the body of rod bottom joint 1 that is connected, all be threaded between the body of rod top sub 3, joint 1 sectorial teeth body top in body of rod bottom does not have shoulder, shoulder is arranged at the sectorial teeth body bottom of body of rod top sub 3, when box cupling 2 is tightened downwards, lock and be positioned on the shoulder of body of rod top sub 3.Preferably 45 ° of angles between two sectorial teeth bodies of body of rod top sub 3 upper ends and joint 1 lower end, body of rod bottom are because at this moment body of rod top sub 3 is realized equal strength with the sectorial teeth body of body of rod bottom joint 1.The shape of cross section of two tooth bodies of body of rod top sub 3 upper ends and joint 1 lower end, body of rod bottom can also be regular polygon or non-regular polygon, is connected but polygonal design should make both embed smoothly.
When using at the scene, be that several same upset forging type anti-loosing solid pumping rod is coupled together use with box cupling, earlier the rotor of the plunger of joint 1 lower end, body of rod bottom and oil pumper or screw pump is linked to each other in the lower going-into-well, again box cupling 2 is connected with body of rod bottom joint 1, rotation box cupling 2, box cupling 2 is moved up along the screw thread of body of rod bottom joint 1, up to the sectorial teeth body that exposes body of rod bottom joint 1, again with the sectorial teeth body of the sectorial teeth body of body of rod bottom joint 1 and body of rod top sub 3 to inserting, rotate box cupling 2 then, make box cupling 2 can with body of rod top sub 3 by being threaded, continue rotation box cupling 2, locking after box cupling 2 is close to the shoulder of body of rod top sub 3, such two sucker rods just connect to get up, remaining sucker rod and the like couple together, in the fillet lower going-into-well of limit, body of rod top sub 3 upper ends of the sucker rod that connects are linked to each other with the power set of oil pumper or screw pump by polished rod can carry out work at last.
