Abstract
A forward and reverse anti-drop sucker rod required for sucker-rod pump oil extraction in the oilfield development process comprises a rotary stop threaded rod (1), a power transmission threaded rod (2), a stress groove (3), a power transmission threaded rod joint shoulder (4), a wrench square neck (5), a flange (6) and a sucker rod body (7), wherein two ends of the sucker rod body (7) are connected with the flange (6) which is larger than the diameter of the excircle of the rod body (7), the rotary stop threaded rod (1) is connected with the power transmission threaded rod (2), the stress groove (3) is arranged between the power transmission threaded rod (2) and the power transmission threaded rod joint shoulder (4), the power transmission threaded rod joint shoulder (4) is connected with the flange (6) through the wrench square neck (5), through adopting the screw thread of different screw directions to reach the purpose of interlocking, and then prevent that the sucker rod from producing relative motion, reach the mesh of anticreep. If the phenomenon that the sucker rod string of the whole shaft is loosened is not to be realized, the plunger, the connecting pull rod and the matched appliance part of the oil well pump need to be correspondingly improved and then are matched with the forward and reverse anti-dropping sucker rod for use.
Description
Technical field
The utility model is a kind of required oil pumping parts of oilfield development process sucker rod pumping that are used for, and concrete land tax is a kind of forward and reverse anticreep sucker rod.
Background technology
Sucker rod pumping is a present domestic and international application mechanical oil recovery method the most widely.This oil production method mainly is by rod string, gives the oil pump plunger piston of down-hole with the transmission of power of surface driving equipment (mainly being oil pumper and screw pump), it is pumped, to reach the purpose of liquid in the tubing string from the shaft bottom pumping to ground.Because oil well can produce borehole track inevitably not in the phenomenon of a vertical line in drilling process, when therefore adopting this kind oil production method to carry out oil well production, can make rod string produce certain moment of torsion, cause rod string in the loosening disengagement of connection of thread, not only influenced the ordinary production of oil well, and security incident can take place when serious, cause unnecessary environmental protection and economic loss.The art of this patent is exactly to solve the problem that rod string is loosening at connection of thread even throw off.
Summary of the invention:
The purpose of this utility model is to provide a kind of forward and reverse anticreep sucker rod, adopt at sucker rod connecting thread place positive and reverse return to, to guarantee in process of production, can not produce the phenomenon that gets loose between the sucker rod, to reach the purpose of anticreep because of relatively rotating.
The utility model is achieved in that and comprises rotation stop threaded rod 1, power transmission threaded rod 2, stress groove 3, power transmission threaded rod joint shoulder 4, spanner square neck 5, flange 6, the sucker rod body of rod 7, the two ends of the sucker rod body of rod 7 are the flanges 6 greater than the body of rod 7 outside diameters, rotation stop threaded rod 1 is connected with power transmission threaded rod 2, be provided with stress groove 3 between power transmission threaded rod 2 and the power transmission threaded rod joint shoulder 4, power transmission threaded rod joint shoulder 4 is connected by spanner square neck 5 with flange 6.
The utility model also adopts following technical scheme:
Power transmission threaded rod 2 is made up of power transmission screw thread 21, rod collar 22, counterbore 23, and rod collar 22 inboards are provided with power transmission screw thread 21, are provided with counterbore 23 in the rod collar 22.
Advantage of the present utility model is to solve common sucker rod in the pumping process, because the effect of moment of torsion, and make sucker rod produce relative motion, the problem that causes rod string to get loose from connection of thread.By adopting the screw thread of different rotation directions, reaching the purpose of interlocking, and then stop sucker rod to produce relative motion, reach the purpose of anticreep.If will realize that the rod string of full pit shaft does not get loose phenomenon, after then need be done corresponding improvement to plunger, cylinder lever connecting rod and the supporting apparatus parts of oil well pump, with the supporting use of forward and reverse anticreep sucker rod.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model power transmission threaded rod 2.
The specific embodiment
As shown in Figure 1, this sucker rod is a symmetrical structure, the two ends of the sucker rod body of rod 7 are the flanges 6 greater than the body of rod 7 outside diameters, rotation stop threaded rod 1 is connected with power transmission threaded rod 2, be provided with stress groove 3 between power transmission threaded rod 2 and the power transmission threaded rod joint shoulder 4, power transmission threaded rod joint shoulder 4 is connected by spanner square neck 5 with flange 6.
As shown in Figure 2, power transmission threaded rod 2 is made up of power transmission screw thread 21, rod collar 22, counterbore 23, and rod collar 22 inboards are provided with power transmission screw thread 21, are provided with counterbore 23 in the rod collar 22.
1. when the oil well commentaries on classics is taken out, a forward and reverse anticreep sucker rod is connected from the plunger of power motion thread bar 2 with oil well pump.
2. rod collar 22 is screwed in power transmission threaded rod 2 places of the forward and reverse anticreep sucker rod of another root from transmission of power screw thread 21, rod collar 22 end faces should retreat to the end face of forward and reverse anticreep sucker rod power transmission threaded rod 2 joint shoulders 4.
3. the rotation stop threaded rod 1 from the forward and reverse anticreep sucker rod of another root screws in rotation stop threaded rod 1 place of the pros-and-cons type anticreep sucker rod that connects with plunger, and reaches the prescribed torque of rotation stop screw thread.
4. transmission of power screw thread 21 places of rod collar 22 to the forward and reverse anticreep sucker rod that connects with plunger are screwed in, rod collar 22 end faces are pressed mutually with the end face of forward and reverse anticreep sucker rod power transmission threaded rod 2 joint shoulders 4, and reach the prescribed torque of transmission of power screw thread.
Can solve sucker rod pump in oil pumping process, because the effect of moment of torsion, sucker rod is applicable to the oil recovery production technology of sucker rod pump from the problem of connection of thread disengagement.
